If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) 19yy name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary.

In mid-May, I asked -Scott Ferris (the official person who's supposed to be writing this -driver) what documentation he used, _finally_ got it from Adaptec, -and started writing this driver.

Code is now present to detect parity -errors, but has not been tested. - -I wrote this using a 1.0.9 kernel. Unfortunately, I'm getting tired of -#ifdef'ing everything to handle two or three different evolutionary steps -in the SCSI kernel code, so I've upgraded my system to 1.1.49, and will -only leave in code to support versions from about 1.1.45 onward. - -Thanks to patches supplied by Mark Olson <molson@tricord.com>, this driver -will now work with the 284x series (the VL-bus version of this card).

GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 675 Mass Ave, Cambridge, MA 02139, USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) 19yy name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - <signature of Ty Coon>, 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

Overview of Startup - ------------------- - - After the system is rebooted, the BIOS bootstrap routine reads Sector - 1, Track 0 into memory at location 0000:7C00H. If location 0000:7DFEH - (last two bytes of that sector) contains the value AA55H, the BIOS - bootstrap routine will transfer control to 0000:7C00H. Otherwise, the - boot code in that sector is bad and the boot routine stops. - - For DOS compatibility reason, one extra stage of boot is required if - the boot device is a hard disk. The first sector of the hard disk will - contain the MOS-DOS boot code and a boot record partition table. - When this sector is loaded into 0000:7C00H, it will relocate itself - to somewhere else and then load the first sector of the active - partition into 0000:7C00H. Both UNIX and DOS use the command "fdisk" -[ 386bsd does not have an 'fdisk' (yet) ] - to install this first sector into the hard disk and to manipulate - the hard disk partitions. - - - -2. The First Stage Bootstrap Loader - -------------------------------- - - After startup, the first stage boot is loaded at 0000:7C00H. This - first stage boot will load itself and the second stage boot into - memory at location 0000:1000H. For floppy disks, the first cylinder - is reserved as the boot cylinder, and the boot code (first and second) - will be loaded from there. Currently, only double sided, high density - (15 sectors per track) floppies are supported. For hard disks, the - first 29 sectors of the active partition is reserved for boot code - which will be loaded by the first stage boot. All the disk types - recognized by BIOS are supported by this bootstrap loader. -[for 386bsd we load the second stage booter to 9000:0] - - - -3. The Second Stage Bootstrap Loader - -------------------------------- - - After the boot code is loaded, the control is passed to the second - stage bootstrap loader "boot2()". In order to be able to load the - big kernel image (bigger than 512K or 640K, depends on the memory - configuration), the second stage boot loader will run on the protected - mode. This bootstarp loader does not have any stand alone device - drivers, all the I/O's are through the BIOS calls. Since the first - stage boot code will no longer be used at this moment, the memory - location of the first stage boot code (0000:1000H to 0000:1200H) will - be used as an internal buffer for BIOS calls. Immediately after this - internal buffer is the GDT table for the second stage boot loader. - Since this boot loader needs to switch back and forth between protected - and real mode in order to use BIOS calls, the limit of the boot code - and boot data segments must not be greater than 64K. - - The boot loader loads the kernel image at memory location above 1 MB - to skip the memory hole between 521K/640K and 1MB. After the kernel - is loaded, the boot loader stores the information in the stack and - then passes control to kernel. Currently, the three information passed - fromm the boot loader to the kernel are type of the boot device, size - of the base memory and size of the extended memory. - -[ 386bsd receives: howto, bootdev] - -[ 386bsd is loaded where-ever the "MByte" bits of the load address specify, -so if you link it for FE100000 it will load to 1MB, but if you link -it for FE000000 it will load ad 0MB] - -[for machines with only 512KB normal ram the kernel will need to be linked -for 1MB and the bootblocks modified to run below 512KB. (8000:0)] - - -4. The UNIX Startup - ---------------- - - Since the boot loader loads the kernel image at memory location above - 1MB, the kernel has to start as protected mode. In addition, the - link editor description file (vuifile) has to indicate that - the text and data segments start above 1MB. Also, the boot loader - passes the infomation to the kernel through the stack. - -[MOST of what is mentionned below is NOT relevant to 386bsd] - -5. Disk Layout and Bad Block Handling - --------------------------------- - - The System V/386 Release 3.2 (AT) disk layout will be used as the disk - layout for the MACH System on the AT platform. - - This disk layout is as follows: - - * Reserve the first sector of cylinder 0 for the DOS boot record which - contains the master boot code (446 bytes) and the partition table. - (Refer to DOS Technical Reference Manual page 9-6 to 9-10). - - * Reserve the first 29 sectors of the UNIX partition for the first - and the second stage bootstrap. - - * Reserve the 30th sector of the UNIX partition for the pdinfo and - the vtoc tables. - - * Reserve the 31st to the 34th sectors of the UNIX partition for the - bad track and the bad block mapping tables. - - * Reserve up to 253 consecutive tracks when required, beginning with - the 35th sector of the UNIX partition, for alternate tracks. - - * Reserve up to 253 consecutive blocks, beginning with the first - sector after the alternate tracks area, for alternate blocks. - - SEC - 1 - ---------------------------------------------------- - | X | | CYL 0, TRK 0 - ---------------- .......... -------------------- - | .......... | - ---------------- .......... -------------------- - | .......... | - =============================================================== - ^ | BOOTSTRAP | CYL N, TRK M - | ---------------------------------------------------- - | | |30 |31 |32 |33 |34 | - ---------------------------------------------------- --- - U | .......... | ^ - N ---------------- .......... --------------------- | - I | .......... | Alternate Tracks - X ---------------- .......... --------------------- | - | .......... | V - P ---------------------------------------------------- --- - A | .......... | ^ - R ---------------- .......... --------------------- | - T | .......... | Alternate Blocks - I ---------------- .......... -------------------- | - T | .......... | V - I ---------------------------------------------------- --- - O | Unix root partition starts from here | - N ---------------- ----------------- - | | - ---------------------------------------------------- - | | - ---------------------------------------------------- - | | - | --------------------------------------------------- - | | | - | ---------------------------------------------------- - V | | - =============================================================== - | ........ | - --------------- ........ -------------- - | ........ | - ---------------------------------------------------- - - - The bad block handling mechanism is as follows: - - * Use the alternate track in the alternate tracks area if the - track containing the target sector is bad. - - * Use the alternate block in the alternate blocks area if the - target sector is bad. - - - - -6.

It allows -SYSVr3.2 i386 binaries (iBCS2 compatible) to run under FreeBSD-2.0. -We haven't been able to do an exhaustive test, of course, but we are able -to run at least the following programs: - - ISC 2.2 sh, vi, dd, date, wc, chmod, etc. - - SCO 3.2v2 runs most (coff) utils on a chroot'ed filesystem - Informix-2.10, gcc, bash, tcsh .... - - SCO 3.2v4 sh, gzip, GNU make, tcsh - -Some of those, for both ISC and SCO, used the shared libraries that are -available for those systems. Currently, the only way to run them, is to -get a copy of the shared libraries in question (e.g. /shlib/libc_s). -There might be a way to generate them from a package available for Linux, -but we haven't had the time or energy to do it ourself, and the last call -for volunteers resulted in nothing. If someone else wants to volunteer, -we would be grateful. - - -How to get it into the system -============================= - -There are two ways of getting iBCS2 support into the system. One is to use -Loadable Kernel Modules (LKM) to put it into the kernel at run-time. This -demands a kernel compiled with: - - options "COMPAT_IBCS2" - -This puts in the nessesary hooks to let the iBCS2 support do its thing. -One loads the iBCS2 support by using the command 'ibcs2' (in /usr/bin). -You can use 'modstat' to see the loaded modules. - -Another way is to compile it into the kernel. This is accomplished using: - - options "COMPAT_IBCS2" - options "IBCS2" - -in the kernel config file. - - -Where's what -============ - -The ibcs2 package consists of quite a few files located in ./sys/i386/ibcs2. -Here is a brief description of them: - -ibcs2.h: Basic header file defines iBCS2 types etc. - -ibcs2_dummy.c: Stubs to system calls not yet supported, or not feasible - to emulate. - -ibcs2_ioctl.c: Probably the single-most complicated part of it, this deals - with translating as many ioctl calls as possible between - BSD and iBCS2. - -ibcs2_misc.c: This has all of the wrapping routines that were thought - "easy" (at least initially) or that didn't fit anywhere else. - -ibcs2_file.c: Functions that deals with file I/O, such as getdents and read - which are more complex than one should expect. - -ibcs2_signal.c: This deals with the signal cruft, including both system - calls and signal translation. - -ibcs2_stats.c: This has all of the filesystem statistic wrappers - (stat, fstat, statfs, etc.). - -ibcs2_sysent.c: This has the system call table for iBCS2 programs, and is - NOT generated automatically. - -ibcs2_ipc.c: Stubs for the iBCS2 ipc calls (shm, msg, sem). - -ibcs2_isc.c: This deals with the ISC specific system call (cisc()). - -ibcs2_sysi86.c: This deals with the i86 specific system call (sysi86()). - -ibcs2_xenix.c: This deals with the Xenix specific system call (cxenix()). - (This also has some of SCO's POSIX-conformant functions.) - -imgact_coff.c: This is the functions that alllows the kernel to load - COFF programs. It also deals with shared library loading. - -There also exist two files (ibcs2_socksys.[ch]) which contains a proto -implementation of the SYSVr3 socket system, donated by Mostyn Lewis -(mostyn@mrl.com). It has not been tested much but is included as a basis -for network support, which is nessesary to run X and the likes. - - -What's Next -=========== - -Much needs to be done yet, mainly the socksys emulation should be looked -at to get socket support going. There currently also is no ipc support. -The sem & msg functions should map fairly easy to the BSD ones, but our -current BSD shm implementation is not even close to SYSV behavior, if it -works at all. -We currently have loaders or "image_activators" for other binary formats, -but none of them is really usefull yet (xout, elf). -Also most of the wrappers for the extra syscalls used by SYSVr4 has been -done, but not much testing yet because of lacks in the elf loader (but it -will run a statically linked SYSVr4 shell). - -All the wrappers should be tested one by one using every aspect of use -by the iBCS2 system. The tests we have done so far is to run small -testprograms to check a limited set of the emulation. When this proved -that the basics was functional, we tried with what iBCS2 programs where -at hand. This is by no means an exhaustive test or to say that the -emulation is errorfree, only a statement of overall functionality of -the emulator. - -Surely much work can be done here, but we are both kind of lazy, and did -the whole thing just for the fun of it, and mainly as a "can it be done" -project. - - Soren Schmidt (sos@login.dknet.dk) - Sean Eric Fagan (sef@kithrup.com) - - diff --git a/sys/i386/ibcs2/ibcs2.h b/sys/i386/ibcs2/ibcs2.h deleted file mode 100644 index 8063c7b..0000000 --- a/sys/i386/ibcs2/ibcs2.h +++ /dev/null @@ -1,280 +0,0 @@ -/*- - * Copyright (c) 1994 Søren Schmidt - * Copyright (c) 1994 Sean Eric Fagan - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.

Donations and - sponsors for projects are appreciated. - - ------------------------------------------------------------------------------ -Edit History - (should be in sync with any source control log entries) - - Never seen one of these before? Ok, here is how it works. - Every time you change the code, you increment the edit number, - that number over there in the <%d> and in the (%d) in the - version string. You never set this number lower than it is. - Near, or preferably on lines that change, insert the edit - number. If there is a number there already, you can replace it - with a newer one. - - In the edit history, start with the edit number, and a good - description of what changes were made. Then follow it with - the date, your name and an EMAIL address where you can be reached. - - Please follow this practice; it helps leave understandable code in - your wake. - - FYI, you have major and minor release codes. These are numbered - 1 thru n. Major feature additions should get a new major release - number. Minor releases start with a null and then letters - A thru Z. So 3A(456) is Major release 3, Minor release 1, - Edit 456 (in Microsoft-ese that would be 03.01.456), and 5(731) - is Major release 5, Minor release 0, Edit 731. Typically only the - author will change the major and minor release codes. - - EDIT edit Edit HISTORY history History - -<1> This initial version is to get basic filesystem I/O working - using the SoundBlaster 16 interface. The stand-alone adapter - card doesn't work yet. - December 1994 Frank Durda IV bsdmail@nemesis.lonestar.org - -<2> Corrections to resolve a race condition when multiple drives - on the same controller was active. Fixed drive 1 & 2 swap - problem. See selectdrive(). - 21-Jan-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -<3> Added automatic probing and support for all Creative Labs sound - cards with the Creative/Panasonic interface and the stand-alone - interface adapters. See AUTOHUNT and FULLCONFIG conditionals - for more information. - 21-Jan-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -<4> Rebundled debug conditionals. - 14-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -<5> Changes needed to work on FreeBSD 2.1. Also added draincmd - since some conditions cause the drive to produce surprise data. - See setmode and draincmd - 19-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -<6> Got rid of some redundant error code by creating chk_error(). - Also built a nice generic buss-lock function. - 20-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -<7> Improved comments, general structuring. - Fixed a problem with disc eject not working if LOCKDRIVE was set. - Apparently the drive will reject an EJECT command if the drive - is LOCKED. - 21-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -Edit number code marking begins here - earlier edits were during development. - -<8> Final device name selected and actually made to compile under - >2.0. For newer systems, it is "matcd", for older it is "mat". - 24-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -<9> Added some additional disk-related ioctl functions that didn't - make it into earlier versions. - 26-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org - -<10> Updated some conditionals so the code will compile under - 1.1.5.1, although this is not the supported platform. - Also found that some other devices probe code was changing the - settings for the port 0x302 debug board, so added code to set it - to a sane state before we use it. - 26-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org - - ----------------------------------------------------------------------------*/ - -/*Match this format: Version__dc(d)__dd-mmm-yy */ -static char MATCDVERSION[]="Version 1(10) 26-Feb-95";

In fact this program - may interpret the modules incorrectly since I am - not a module player expert. - This version plays .MOD, .STM and .669 modules. - -midithru.c This program reads messages from the Midi interface - and plays the notes with an internal synthesizer - (FM or GUS). The program accepts one argument, the - synthesizer device number. In addition to the note on - and note off messages it interprets also program changes - and channel pressure messages. - If you need an example on programming the /dev/sequencer, - this is a good one. The voice allocation algorithm is - not good so don't look at it. - - NOTE! This program is useful with gmod. Jus load - a module with gmod. Wait until the module has - finished or hit ^C. Now you can play the samples - with the midithru program. - - NOTE2! You need a Midi keyboard to use this program. In - addition the Midi interface of GUS is not supported - yet which means you need also PAS16 or MPU-401. - -pmtest.c -gpatinfo.c ******* For information only ******* - These programs demonstrate the patch manager interface - which will be included to some later driver version. - This interface is not complete in version 1.99.9. - Using pmtest will hang your system sooner or later. - -Hannu Savolainen -hsavolai@cs.helsinki.fi diff --git a/sys/i386/isa/sound/gustest/gmidi.h b/sys/i386/isa/sound/gustest/gmidi.h deleted file mode 100644 index 106cfa2..0000000 --- a/sys/i386/isa/sound/gustest/gmidi.h +++ /dev/null @@ -1,134 +0,0 @@ -/* - * $Id$ - */ - char patch_names[][9] = - { - /* 0 */ "acpiano", - /* 1 */ "britepno", - /* 2 */ "synpiano", - /* 3 */ "honktonk", - /* 4 */ "epiano1", - /* 5 */ "epiano2", - /* 6 */ "hrpschrd", - /* 7 */ "clavinet", - /* 8 */ "celeste", - /* 9 */ "glocken", - /* 10 */ "musicbox", - /* 11 */ "vibes", - /* 12 */ "marimba", - /* 13 */ "xylophon", - /* 14 */ "tubebell", - /* 15 */ "santur", - /* 16 */ "homeorg", - /* 17 */ "percorg", - /* 18 */ "rockorg", - /* 19 */ "church", - /* 20 */ "reedorg", - /* 21 */ "accordn", - /* 22 */ "harmonca", - /* 23 */ "concrtna", - /* 24 */ "nyguitar", - /* 25 */ "acguitar", - /* 26 */ "jazzgtr", - /* 27 */ "cleangtr", - /* 28 */ "mutegtr", - /* 29 */ "odguitar", - /* 30 */ "distgtr", - /* 31 */ "gtrharm", - /* 32 */ "acbass", - /* 33 */ "fngrbass", - /* 34 */ "pickbass", - /* 35 */ "fretless", - /* 36 */ "slapbas1", - /* 37 */ "slapbas2", - /* 38 */ "synbass1", - /* 39 */ "synbass2", - /* 40 */ "violin", - /* 41 */ "viola", - /* 42 */ "cello", - /* 43 */ "contraba", - /* 44 */ "marcato", - /* 45 */ "pizzcato", - /* 46 */ "harp", - /* 47 */ "timpani", - /* 48 */ "marcato", - /* 49 */ "slowstr", - /* 50 */ "synstr1", - /* 51 */ "synstr2", - /* 52 */ "choir", - /* 53 */ "doo", - /* 54 */ "voices", - /* 55 */ "orchhit", - /* 56 */ "trumpet", - /* 57 */ "trombone", - /* 58 */ "tuba", - /* 59 */ "mutetrum", - /* 60 */ "frenchrn", - /* 61 */ "hitbrass", - /* 62 */ "synbras1", - /* 63 */ "synbras2", - /* 64 */ "sprnosax", - /* 65 */ "altosax", - /* 66 */ "tenorsax", - /* 67 */ "barisax", - /* 68 */ "oboe", - /* 69 */ "englhorn", - /* 70 */ "bassoon", - /* 71 */ "clarinet", - /* 72 */ "piccolo", - /* 73 */ "flute", - /* 74 */ "recorder", - /* 75 */ "woodflut", - /* 76 */ "bottle", - /* 77 */ "shakazul", - /* 78 */ "whistle", - /* 79 */ "ocarina", - /* 80 */ "sqrwave", - /* 81 */ "sawwave", - /* 82 */ "calliope", - /* 83 */ "chiflead", - /* 84 */ "voxlead", - /* 85 */ "voxlead", - /* 86 */ "lead5th", - /* 87 */ "basslead", - /* 88 */ "fantasia", - /* 89 */ "warmpad", - /* 90 */ "polysyn", - /* 91 */ "ghostie", - /* 92 */ "bowglass", - /* 93 */ "metalpad", - /* 94 */ "halopad", - /* 95 */ "sweeper", - /* 96 */ "aurora", - /* 97 */ "soundtrk", - /* 98 */ "crystal", - /* 99 */ "atmosphr", - /* 100 */ "freshair", - /* 101 */ "unicorn", - /* 102 */ "sweeper", - /* 103 */ "startrak", - /* 104 */ "sitar", - /* 105 */ "banjo", - /* 106 */ "shamisen", - /* 107 */ "koto", - /* 108 */ "kalimba", - /* 109 */ "bagpipes", - /* 110 */ "fiddle", - /* 111 */ "Shannai", - /* 112 */ "carillon", - /* 113 */ "agogo", - /* 114 */ "steeldrm", - /* 115 */ "woodblk", - /* 116 */ "taiko", - /* 117 */ "toms", - /* 118 */ "syntom", - /* 119 */ "revcym", - /* 120 */ "fx-fret", - /* 121 */ "fx-blow", - /* 122 */ "seashore", - /* 123 */ "jungle", - /* 124 */ "telephon", - /* 125 */ "helicptr", - /* 126 */ "applause", - /* 127 */ "ringwhsl" - }; diff --git a/sys/i386/isa/sound/gustest/gmod.c b/sys/i386/isa/sound/gustest/gmod.c deleted file mode 100644 index 2988783..0000000 --- a/sys/i386/isa/sound/gustest/gmod.c +++ /dev/null @@ -1,1589 +0,0 @@ -/* - * gmod.c - Module player for GUS and Linux. - * (C) Hannu Savolainen, 1993 - * - * NOTE!
