Technical overview +--------------------- + +FreeBSD is a freely available, full source 4.4 BSD Lite based release +for Intel i386/i486/Pentium (or compatible) based PC's. It is based +primarily on software from U.C. Berkeley's CSRG group, with some +enhancements from NetBSD, 386BSD, and the Free Software Foundation. + +Since our first release of FreeBSD 1.0 some 18 months ago, FreeBSD +has changed almost entirely. A new port from the Berkeley 4.4 code +base was done, which brought the legal status of the system out of the +shadows with the blessing of Novell (new owners of USL and UNIX). The +port to 4.4 has also brought in a host of new features, filesystems +and enhanced driver support. With our new unencumbered code base, we +have every reason to hope that we'll be able to release quality +operating systems without further legal encumbrance for some time to +come! + +FreeBSD 2.0 represents the culmination of almost 2 years of work and +many thousands of man hours put in by an international development team. +We hope you enjoy it! + +Many packages have also been upgraded or added, such as XFree86 3.1, +xview 3.2, elm, nntp, mh, InterViews and dozens of other miscellaneous +utilities have been ported and are now available as add-ons. See the +ports collection (or the package collection) for a complete summary. + +For a list of contributors and a general project description, please see +the file "CONTRIB.FreeBSD" which should be bundled with your binary +distribution. + +Also see the "REGISTER.FreeBSD" file for information on registering +with the "Free BSD user counter". This counter is for ALL freely +available variants of BSD, not just FreeBSD, and we urge you to register +yourself with it. + +The core of FreeBSD does not contain DES code which would inhibit its +being exported outside the United States. There is an add-on package +to the core distribution, for use only in the United States, that +contains the programs that normally use DES. The auxilliary packages +provided separately can be used by anyone. A freely (from outside the +U.S.) exportable European distribution of DES for our non U.S. users also +exists and is described in the FreeBSD FAQ. + +If password security for FreeBSD is all you need, and you have no +requirement for copying encrypted passwords from different hosts (Suns, +DEC machines, etc) into FreeBSD password entries, then FreeBSD's MD5 +based security may be all you require! We feel that our default security +model is more than a match for DES, and without any messy export issues +to deal with. If you're outside (or even inside) the U.S., give it a try! + + +1.1 What's new in 2.0? +---------------------- + +4.4 Lite +-------- +As previously stated, this release is based entirely on CSRG's +latest (and last) BSD release - 4.4 Lite. This features a number +of improvements over 4.2BSD (Net/2), not least of which are: + +o Legal approval of Novell & U.C. Berkeley. After the settlement + of the longstanding lawsuit between USL/UCB/Novell/BSDI, all + parties were (strongly) encouraged to move to 4.4 Lite in order + to avoid future legal entanglements. The fact that we've now done + so should make this release much more attractive to potential + commercial users. + +o Many new filesystem types, such as stackable filesystems, union + filesystems, "portals", kernfs, a simple log-structured filesystem, a + new version of NFS (NQNFS), etc. While some of these new filesystems + are also rather unpolished and will require significant additional + work to be truly robust, they're a good start. + +o 64bit offsets, allowing filesystems of up to 2^63 bytes in size. + +o Further work towards full POSIX compliance. + +IP multicast support +-------------------- +The IP multicast support has been upgraded from the woefully ancient +1.x code in 4.4-Lite to the most current and up-to-date 3.3 release +from Steve D. and Ajit. The non-forwarding code is known to work (for +some limited test cases). The multicast forwarder and user-mode +multicast routing process are known to compile, but have not been +significantly tested (hopefully this will happen before 2.0 release). + +Owner: wollman +Sources involved: sys/netinet, usr.sbin/mrouted + +Loadable Kernel Modules +----------------------- +David Greenman incorporated NetBSD's port of Terry Lambert's loadable +kernel module support. Garrett Wollman wrote the support for loadable +file systems, and Søren Schmidt did the same for loadable execution +classes. + +Owner: core +Sources involved: sys/kern, sbin/modload, sbin/modunload, + usr.bin/modstat + + +Loadable filesystems +-------------------- +Most filesystems are now dynamically loadable on demand, with the +exception of the UFS family (FFS, LFS, and MFS). With the exception +of NFS, all such filesystems can be unloaded when all references are +unmounted. To support this functionality, the getvfsbyname(3) +family of functions has been added to the C library and the lsvfs(1) +command provides the same information at the shell level. Be aware of +the following current restrictions: + + - /usr/bin may not reside on a dynamically loaded filesystem. + - There must be a writable /tmp directory available + before filesystems are loaded (moving / to the top of your + /etc/fstab file will accomplish this). + - Some of the more esoteric filesystems simply don't work when loaded + dynamically (though they often don't work "static", either.) + +Owner: wollman +Sources involved: sys/*fs, lkm/*fs, usr.bin/lsvfs, lib/libc/gen + + +S/Key +----- +Since version 1.1.5, FreeBSD has supported the S/Key one time password +scheme. The version used is derived from the logdaemon package of Wietse +Venema. +Some of the features new in 2.0 are: + - New access control table format to impose the use of S/Keys + based on: hostname, ip address, port, username, group id. + - S/Key support can be disabled by not having the access control + table. +The second item explains the absence of skey.access in the installed /etc. +To enable S/Key support, create a file skey.access in /etc and fill it +according to your needs. See also skey.access(5) and the example in +/usr/share/examples/etc/skey.access. + +Owner: pst, guido +Sources involved: lib/libskey, usr.bin/key* (plus patches to others) + + +TCP/IP over parallel (printer) port +----------------------------------- +You can now run TCP/IP over a standard LapLink(tm) cable, if both ends +have an interrupt-driven printerport. The interface is named "lp0" +where '0' is the same as the lpt# unit number. This is not compatible +with PLIP. If you run NFS, try setting MTU to 9180, otherwise leave +it at 1500 unless you have a good reason to change it. Speed varies +with the CPU-type, with up to 70 kbyte/sec having been seen and 50 +kbyte/sec being the norm. + +Owner: phk +Sources involved: isa/lpt.c + + +ProAudioSpectrum SCSI driver +---------------------------- +If you have a PAS board with a CD-ROM, and the MS-DOS driver is called +TSLCDR.SYS, then the "pas" driver should work on your card. You can +attach disks, cdroms and tapes, but due to the nature of the hardware +involved, the transfer rate is limited to < 690 kbyte/sec. For CD-ROM +use, this is generally more than enough. + +Owner: phk +Sources involved: isa/pas.c + + +Adaptec 2742/2842 SCSI driver +----------------------------- +Despite the non-cooperation of Adaptec in providing technical +information, we now have a driver for the AHA-274x and AHA-284x +series SCSI controller family. This driver uses the GPL'd +Linux sequencer code, so until we find an alternative, this +will be part of the kernel that requires source code to be +distributed with it at all times. This shouldn't be a problem +for any of FreeBSD's current users. + +Owner: gibbs +Sources involved: isa/aic7770.c sys/gnu/misc/* + + +Gzip'd binaries +---------------- +We have an experimental implementation for direct execution of gzip'ed +binaries in this release. When enabled, it allows you to simply gzip +your binaries, remove the '.gz' extension and make the file +executable. There is a big speed and memory consumption penalty for +doing this, but for laptop users it may be worthwhile. The maximum +savings are generally around 10 Mb of disk space. + +Owner: phk +Sources involved: kern/imgact_gzip.c kern/inflate.c + + +Diskless booting +---------------- + +Diskless booting in 2.0 is much improved since 1.1.5. The +boot-program is in src/sys/i386/boot/netboot, and can be run from an +MSDOS system or burned into an EPROM. Local swapping is also +possible. WD, SMC, 3COM and Novell ethernet cards are currently +supported. + +Owner: Martin Renters & phk +Sources involved: i386/boot/netboot, sys/nfs/nfs_vfsops.h + + +Device configuration database +----------------------------- +The kernel now keeps better track of which device drivers are active and +where the devices are attached; this information is made available to +user programs via the new sysctl(3) management interface. Current +applications include lsdev(8), which lists the currently configured +devices. In the future, we expect to use this code to automatically +generate a configuration file for you at installation time. + +Owner: wollman +Sources involved: sys/i386, sys/scsi, sys/kern/kern_devconf.c, + sys/sys/devconf.h, usr.sbin/lsdev + + +Kernel management interface +--------------------------- +With 4.4-Lite, we now have a better management interface for the endless +series of kernel variables and parameters which were previously manipulated +by reading and writing /dev/kmem. Many programs have been rewritten to +use this interface, although many old-style programs still remain. Some +variables which were never accessible before are now available through +the sysctl(1) program. In addition to the standard 4.4BSD MIB variables, +we have added support for YP/NIS domains (kern.domainname), controlling +the update daemon (kern.update), retrieving the OS release date +(kern.osreldate), determining the name of the booted kernel (kern.bootfile), +and checking for hardware floating-point support (hw.floatingpoint). +We have also added support to make management queries of devices and +filesystems. + +Owner: core +Sources involved: sys, usr.bin/sysctl + + +iBCS2 support +------------- +FreeBSD now supports running iBCS2 compatible binaries (currently +SCO UNIX 3.2.2 & 3.2.4 and ISC 2.2 COFF format are supported). +The iBCS2 emulator is in its early stages, but it is functional, we +haven't been able to do exhaustive testing (lack of commercial apps), +but almost all of SCO's 3.2.2 binaries are working, so is an old +INFORMIX-2.10 for SCO. Further testing is nessesary to complete this +project. There is also work under way for ELF & XOUT loaders, and +most of the svr4 syscall wrappers have been written. + +Owner: Soren Schmidt (sos) & Sean Eric Fagan (sef) +Sources involved: sys/i386/ibcs2/* + misc kernel changes. + + +2. Supported Configurations +--------------------------- + +FreeBSD currently runs on a wide variety of ISA, VLB, EISA and PCI bus +based PC's, ranging from 386sx to Pentium class machines (though the +386sx is not recommended). Support for generic IDE or ESDI drive +configurations, various SCSI controller, network and serial cards is +also provided. + +Following is a list of all currently known disk controllers and +ethernet cards known to work with FreeBSD. Other configurations may +very well work, and we have simply not received any indication of +this. + + +2.1. Disk Controllers + +WD1003 (any generic MFM/RLL) +WD1007 (any generic IDE/ESDI) +[Note: the new Extended IDE controllers in newer PC's work, although no +extended features are used.] + +Adaptec 152x series ISA SCSI controllers +Adaptec 154x series ISA SCSI controllers +Adaptec 174x series EISA SCSI controller in standard and enhanced mode. +Adaptec 2742/2842 series ISA/EISA SCSI controllers +Adaptec AIC-6260 and AIC-6360 based boards, which includes +the AHA-152x and SoundBlaster SCSI cards. + +** Note: You cannot boot from the Soundblaster cards +as they have no on-board BIOS, which is necessary for mapping +the boot device into the system BIOS I/O vectors. +They're perfectly usable for external tapes, CDROMs, etc, +however. The same goes for any other AIC-6x60 based card +without a boot ROM. Some systems DO have a boot ROM, which +is generally indicated by some sort of message when the system +is first powered up or reset. Check your system/board documentation +for more details. + +[Note that Buslogic was formerly known as "Bustec"] +Buslogic 545S & 545c +Buslogic 445S/445c VLB SCSI controller +Buslogic 742A, 747S, 747c EISA SCSI controller. +Buslogic 946c PCI SCSI controller + +NCR 53C810 and 53C825 PCI SCSI controller. + +DTC 3290 EISA SCSI controller in 1542 emulation mode. + +UltraStor 14F, 24F and 34F SCSI controllers. + +Seagate ST01/02 SCSI controllers. + +Future Domain 8xx/950 series SCSI controllers. + +With all supported SCSI controllers, full support is provided for +SCSI-I & SCSI-II peripherals, including Disks, tape drives (including +DAT) and CD ROM drives. Note: This and the mcd driver (Mitsumi CDROM +interface card) are the only way a CD ROM drive may be currently +attached to a FreeBSD system; we do not support SoundBlaster +(non-SCSI) CDROM interface, or other "non-SCSI" adapters. The +ProAudio Spectrum SCSI and SoundBlaster SCSI controllers are +supported. + +Some controllers have limitations with the way they deal with >16MB of +memory, due to the fact that the ISA bus only has a DMA address space of +24 bits. If you do your arithmetic, you'll see that this makes it +impossible to do direct DMA to any address >16MB. This limitation is +even true of some EISA controllers (which are normally 32 bit) when +they're configured to emulate an ISA card, which they then do in *all* +respects. This problem is avoided entirely by IDE controllers (which do +not use DMA), true EISA controllers (like the UltraStor or Adaptec +1742A) and most VLB (local bus) controllers. In the cases where it's +necessary, the system will use "bounce buffers" to talk to the +controller so that you can still use more than 16Mb of memory without +difficulty. + + +2.2. Ethernet cards + +SMC Elite 16 WD8013 ethernet interface, and most other WD8003E, +WD8003EBT, WD8003W, WD8013W, WD8003S, WD8003SBT and WD8013EBT +based clones. SMC Elite Ultra is also supported. + +DEC EtherWORKS III NICs (DE203, DE204, and DE205) +DEC EtherWORKS II NICs (DE200, DE201, DE202, and DE422) + +Isolan AT 4141-0 (16 bit) +Isolink 4110 (8 bit) + +Novell NE1000, NE2000, and NE2100 ethernet interface. + +3Com 3C501 cards + +3Com 3C503 Etherlink II + +3Com 3C507 Etherlink 16/TP + +3Com 3C509 and 3C579 Etherlink III + +Toshiba ethernet cards + +PCMCIA ethernet cards from IBM and National Semiconductor are also +supported. + +2.3. Misc + +AST 4 port serial card using shared IRQ. + +ARNET 8 port serial card using shared IRQ. + +BOCA ATIO66 6 port serial card using shared IRQ. + +STB 4 port card using shared IRQ. + +Mitsumi (all models) CDROM interface and drive. + +Soundblaster SCSI and ProAudio Spectrum SCSI CDROM interface and drive. + +Adlib, Soundblaster, Soundblaster Pro, ProAudioSpectrum, Gravis UltraSound +and Roland MPU-401 sound cards. + +FreeBSD currently does NOT support IBM's microchannel (MCA) bus, but +support is apparently close to materializing. Details will be posted +as the situation develops. + + +3. Obtaining FreeBSD. +--------------------- + +You may obtain FreeBSD in a variety of ways: + +1. FTP/Mail + +You can ftp FreeBSD and any or all of its optional packages from +`freebsd.cdrom.com' - the offical FreeBSD release site. + +For other locations that mirror the FreeBSD software see the file +MIRROR.SITES. Please ftp the distribution from the nearest site +to you netwise. + +If you do not have access to the internet and electronic mail is your +only recourse, then you may still fetch the files by sending mail to +`ftpmail@decwrl.dec.com' - putting the keyword "help" in your message +to get more information on how to fetch files from freebsd.cdrom.com. +Note: This approach will end up sending many *tens of megabytes* +through the mail, and should only be employed as an absolute LAST +resort! + + +2. CDROM + +FreeBSD 2.0 may be ordered on CDROM from: + + Walnut Creek CDROM + 4041 Pike Lane, Suite D + Concord CA 94520 + 1-800-786-9907, +1-510-674-0783, +1-510-674-0821 (fax) + +Or via the internet from orders@cdrom.com. Their current catalog can +be obtained via ftp as ftp.cdrom.com:/cdrom/catalog. + +Cost is $39.95. Shipping (per order not per disc) is $5 in the US, Canada, +or Mexico and $10.00 overseas. They accept Visa, Mastercard, American +Express, and ship COD to the United States. California residents please +add 8.25% sales tax. + +Should you be dissatisfied for any reason, the CD comes with an +unconditional return policy. + +Note that Walnut Creek CDROM does NOT provide technical support for FreeBSD, +you need to contact the FreeBSD team for that. Please see section 5 for +more information. + + +4. Preparing for the installation. +---------------------------------- + +1. Floppy Installation + +If you must install from floppy disks, either due to space contraints +on your hard disk or just because you enjoy doing things the hard +way, you must first prepare some floppies for the install. + +You will need either 10 1.44MB floppies or 12 1.2MB floppies to +store just the bindist (binary distribution). These *must* be +formatted using MS-DOS, using either the FORMAT command in MS-DOS +or the File Manager in Microsoft Windows to prepare the floppies +(though factory preformatted floppies will also well well, provided +that they haven't been previously used for something else). + +After you've formatted the floppy disks, you'll need to copy the +files onto them. There are 56 total files for the bindist itself, +plus three small files (CKSUMS, do_cksum.sh, and extract.sh) for +the install program to use. ALL of these files must be copies onto +the floppies. Each of the bindist files are named "bindist.??", +where the "??" is replaced by the letter sequence aa through cd. +Copy these files onto the floppies, placing the three small install +files onto the final floppy. The order in which you copy the files +to floppy is not important, but it makes labelling the disks easier +if you go in some sort of alphabetical order. + +After you've done this, the floppy disks are ready for the install +program to use. + +Later on, after you get the binary distribution installed and everything +is going great, the same instructions will apply for the other +distributions, such as the manpages distribution or the XFree86 distribution. +The number of floppies required will, of course, change for bigger or +smaller distributions. + + +2. Hard Disk Installation + +To prepare for installation from an MS-DOS partition, you should simply +copy the files from the distribution into a directory with the same +name as the distribution. For example, if you are preparing to +install the bindist set, then make a directory on your C: drive named +C:\BINDIST and copy the files there. This will allow the installation +program to find the files automatically. + + +3. QIC/SCSI Tape Installation. + +Installing from tape is probably the easiest method, short of an +on-line install using ftp or installing from a CDROM. The installation +program expects the files to be simply tar'red onto the tape, so after +getting all of the files for distribution you're interested in, simply +tar them onto the tape with something like: + + cd <where the *.?? files are> + tar cvf /dev/rwt0 (or /dev/rst0) . + +from a directory with just the distribution files in it. Make sure +that you remember to put CKSUMS, do_cksum.sh, and extract.sh files +in this directory as well! + +If you wish to install multiple *dist releases from one tape, do the +following: + +1. cd to the parent directory of the distributions and put them on tape + like so: + tar cvf /dev/rwt0 (or /dev/rst0) bindist srcdist ... + +2. Install the first distribution on the tape using the tape installation + method as normal. Afterwards, *do not* erase the contents of the temporary + directory. Get a shell with ESC-ESC and cd to the temporary directory + yourself. For each additional *dist you want to load, cd to its + subdirectory and type `sh ./extract.sh'. + + +5. Reporting problems, making suggestions, submitting code. +----------------------------------------------------------- + +Your suggestions, bug reports and contributions of code are always +valued - please do not hesitate to report any problems you may find +(preferably with a fix attached if you can!). + +The preferred method to submit bug reports from a machine with internet +mail connectivity is to use the send-pr command. Bug reports will be +dutifully filed by our faithful bugfiler program and you can be sure +that we'll do our best to respond to all reported bugs as soon as +possible. + +If, for some reason, you are unable to use the send-pr command to +submit a bug report, you can try to send it to: + + bugs@FreeBSD.org + + +Otherwise, for any questions or suggestions, please send mail to: + + questions@FreeBSD.org + +Additionally, being a volunteer effort, we are always happy to have +extra hands willing to help - there are already far more enhancements +to be done than we can ever manage to do by ourselves! To contact us +on technical matters, or with offers of help, you may send mail to: + + hackers@FreeBSD.org + +Since these mailing lists can experience significant amounts of +traffic, if you've got slow or expensive mail access and you're +only interested in keeping up with significant FreeBSD events, you may +find it preferable to subscribe to: + + announce@FreeBSD.org + + +All but the FreeBSD-bugs groups can be freely joined by anyone wishing +to do so. Send mail to MajorDomo@FreeBSD.org and include the keyword +`help' on a line by itself somewhere in the body of the message. This +will give you more information on joining the various lists, accessing +archives, etc. There are a number of mailing lists targeted at +special interest groups not mentioned here, so send mail to majordomo +and ask about them! + + +6. Acknowledgements +------------------- + +FreeBSD represents the cumulative work of many dozens, if not +hundreds, of individuals from around the world who have worked very +hard to bring you this release.
