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.

This feature -is provided for the benefit of people who wish to install FreeBSD on -dedicated file/compute/terminal server machines that have no keyboard -(or monitor) attached, just as is possible with Sun workstations and -servers. People who don't need this extra functionality shouldn't notice -the changes at all (unless I've screwed something up horribly). - -To boot FreeBSD in serial console mode, you must do the following: - -- UNPLUG YOUR KEYBOARD. Most PC systems probe for the keyboard during the - Power-On Self-Test (POST) and will generate an error if the keyboard - isn't detected. Some BIOSes may be set to ignore this error. Many other - machines will pause the boot process and wait for you to reattach the - keyboard and press a key before proceeding any further. Consult the manual - of your motherboard to see how it responds to the error and how to - set the BIOS to ignore the error. If your computer complains about - the lack of a keyboard but boots anyway, then you don't have to do - anything special. (One machine with a PHOENIX BIOS that I have here - merely says 'Keyboard failed' then continues to boot normally.) If your - machine complains loudly about the lack of a keyboard and won't continue - to boot until you plug it back in, you'll have to go into your CMOS - configuration menu and change the 'Keyboard' setting to 'Not installed' - in order to bypass the keyboard probe. - - NOTE #1: - Setting the keyboard to 'Not installed' in the CMOS configuration - does *NOT* mean that you won't be able to use your keyboard. All this - does is tell the BIOS not to probe for a keyboard at power-on so that - it won't bitch and moan if the keyboard isn't plugged in. You can leave the - keyboard plugged in even with this flag set to 'Not installed' and the - keyboard will still work. I repeat: changing the CMOS 'keyboard' setting - to 'Not installed' only disables the BIOS's keyboard probe; it does - *NOT* actually disable the keyboard. - - NOTE #2: - If your system has a PS/2 mouse, chances are very good that you will - need to unplug your mouse as well as your keyboard. This is because - PS/2 mice share some hardware with the keyboard, and leaving the mouse - plugged in can fool the keyboard probe into thinking the keyboard is - still there. I have access to a Gateway 2000 Pentium 90Mhz system with - an AMI BIOS that behaves this way. In general this is not a problem - since the mouse isn't much good without the keyboard anyway. - -- PLUG A DUMB TERMINAL INTO COM1. If you don't have a dumb terminal, you - can use an old PC/XT with a modem program, or the serial port on - another UNIX box. If you don't have a COM1, get one. At this time, - there is no way to select a port other than COM1 for the boot blocks - without recompiling the boot blocks. If you're already using COM1 for - another device, you'll have to temporarily remove that device and - install a new boot block and kernel once you get FreeBSD up and running. - (It is assumed that COM1 will be available on a file/compute/terminal - server anyway; if you really need COM1 for something else (and you can't - switch that something else to COM2), then you probably shouldn't even - be bothering with all this in the first place.) - - NOTE #1: - The serial port settings are hardcoded to 9600 baud, 8 bits, no parity, - 1 stop bit, by default. If you wish to change the speed, you need to - recompile at least the boot blocks. Add the following line to - /etc/make.conf and compile new boot blocks: - - BOOT_COMCONSOLE_SPEED=115200 - - If the serial console is configured in some other way than by booting with - -h, or if the serial console used by the kernel is different from the one - used by the boot blocks, then you must also add the following option to the - kernel configuration file and compile a new kernel: - - options CONSPEED=115200 - - NOTE #2: - In addition to a serial cable, you will need a null modem adapter - in order to connect the terminal to the PC's serial port. If you don't - have one, go to Radio Shack and buy one: they're cheap. - - NOTE #3: - If you wish to drop into the kernel debugger from the serial console - (useful for remote diagnostics, but also dangerous if you generate a - spurious BREAK on the serial port!) then you should compile your kernel - with the following options: - - options BREAK_TO_DEBUGGER - options DDB - - -- MAKE SURE THE CONFIGURATION FILE OF YOUR KERNEL HAS APPROPRIATE FLAGS - SET FOR COM1. - - Relevant `flags' are: - 0x10 enable console support for this unit. The other console flags - are ignored unless this is set. Currently, at most one unit can - have console support; the first one (in config file order) with - this flag set is preferred. This option alone will not make - the serial port the console. Set the following flag or use the -h - option described below, together with this flag. - 0x20 force this unit to be the console (unless there is another - higher priority console). This replaces the COMCONSOLE option. - - Example: - device sio0 at isa? port "IO_COM1" tty flags 0x10 irq 4 - - If the flags were not set, you need to run UserConfig (on a different - console) or recompile the kernel. - -- CREATE THE FILE "boot.config" IN THE ROOT DIRECTORY of the `a' partition - on the boot drive. Put the kernel name and options in one line. The - kernel name is optional. Options are subset of those described in boot(8): - -h toggle internal and serial consoles. You can use this to switch - console devices. For instance, if you boot from the VGA console, - you can use -h to force the kernel to use the serial port as its - console device. Alternatively, if you boot from the serial port, - you can use the -h to force the kernel to use the VGA display - as the console instead. (Can you say 'toggle' boys and girls? - I knew you could. :) - -D toggle single and dual console configurations. In the single - configuration the console will be either the VGA display (internal - console) or the serial port, depending on the state of the -h option - above. In the dual console configuration, both the VGA display - and the serial port will become the console at the same time, - regardless of the state of the -h option. - However, the dual console configuration takes effect only during - the boot prompt. Once the kernel is loaded, the console specified - by the -h option becomes the only console. - -P probe the keyboard. If no keyboard is found, the -D and -h options - are automatically set. - - Use either the -P option to select the console automatically, or the -h - option to force the serial console. - -- BOOT THE MACHINE. You'll see a prompt appear on the terminal that looks - something like this: - - No keyboard found - - >> FreeBSD BOOT @ 0x10000: 640/7168 k of memory, serial console - Boot default: 0:wd(0,a)kernel - - boot: - - This is identical to the prompt that normally appears on the VGA console, - except for the 'No keyboard found' message that indicates a keyboard - couldn't be detected, if the -P option is in `boot.config'. - - From here you can boot the system (or let it autoboot by itself) just - like you can from the VGA console and the kernel will automatically - use COM1 as the console device. This is done by passing a special flag - to the kernel in the 'boothowto' word. (The curious can refer to - <sys/reboot.h> and the sio driver sources for details.) - - -CAVEATS: - -- The idea here is to allow people to set up dedicated servers that require - no graphics hardware or attached keyboards. Unfortunately, while (most?) - every system will let you boot without a keyboard, there are quite a few - that will not let you boot without a graphics adapter. Machines with - AMI BIOSes can be configured to boot with no graphics adapter installed - simply by changing the 'graphics adapter' setting in the CMOS configuration - to 'Not installed.' However, many machines do not support this option - and will refuse to boot if you have no display hardware in the system. With - these machines, you'll have to leave some kind of graphics card plugged in, - (even if it's just a junky mono board) although you won't have to attach - a monitor into it. You might also try installing an AMI BIOS. :) - -- Using a port other than COM1 as the console requires some recompiling. - Again, it's usually assumed that COM1 will be available for use as a - console device on a dedicated file/compute/terminal server, so hopefully - you'll never need to do this. But if you feel you must change the console - to a different port, here's how: - - o Get the kernel source package. - o Edit /etc/make.conf and set BOOT_COMCONSOLE_PORT to the - address of the port you want to use (0x3F8, 0x2F8, 0x3E8 or - 0x2E8). Only COM1 through COM4 can be used; multiport serial - cards will not work. No interrupt setting is needed. - o Create a custom kernel configuration file and add appropriate - `flags' for the serial port you want to use. For example, if you - want to make COM2 the console: - - device sio1 at isa? port "IO_COM2" tty flags 0x10 irq 3 - - The console flags for the other serial ports should not be set. - o Recompile both the boot blocks and the kernel. - o Install the boot blocks with the disklabel command and boot - from the new kernel. - - -$FreeBSD$ diff --git a/sys/i386/boot/biosboot/asm.S b/sys/i386/boot/biosboot/asm.S deleted file mode 100644 index f14c7f5..0000000 --- a/sys/i386/boot/biosboot/asm.S +++ /dev/null @@ -1,244 +0,0 @@ -/* - * Mach Operating System - * Copyright (c) 1992, 1991 Carnegie Mellon University - * All Rights Reserved. - * - * Permission to use, copy, modify and distribute this software and its - * documentation is hereby granted, provided that both the copyright - * notice and this permission notice appear in all copies of the - * software, derivative works or modified versions, and any portions - * thereof, and that both notices appear in supporting documentation. - * - * CARNEGIE MELLON ALLOWS FREE USE OF THIS SOFTWARE IN ITS "AS IS" - * CONDITION.

-
-This is version 1.5 of "fbsdboot", a program that allows you to boot a kernel
-from a MS-DOS partition or a FreeBSD partition. This program runs using DOS.
-It works with various memory managers (like EMM386, 386MAX) under certain
-circumstances.
-
-First, a FreeBSD kernel is always loaded to memory starting at 0x100000. To
-assure that loading the kernel *does not* overwrite memory used by memory
-managers, high memory for the kernel is allocated and after loading the kernel
-it's moved to 0x100000.
-
-Second, there are many ways to switch to protected mode which is necessary to
-start the kernel. Each BIOS gives you the possibility to use INT15H (AH=89H)
-to do that. But some memory-managers like 386max does not allow you to use
-this method.
-
-An other way to do the switch is to use DPMI services, but they do not
-guarantee, that the protected mode application is executed with privilege
-level 0. Therefore this method is *not* used.
-
-VCPI services offer another way to switch to protected mode, and VCPI servers
-are built into "emm386.exe", "386max" and "qemm". That's why, this method is
-implemented in fbsdboot.exe.
-
-Fbsdboot.exe tries to switch to protected mode using VCPI services. If they're
-not available INT15H is used to do the switch. If that fails, it's not possible
-for this version of fbsdboot.exe to boot a kernel :-(.
-
-You can get commandline options of fbsdboot if you start it with "-?" as option!
-
-I don't know, if fbsdboot works with QEMM, as I don't have the possibility to
-test it.
-
-Enjoy and have fun!
-
-Christian.
