9ed24653f7 Obtained from: Whistle Communications
Add code to the boot blocks to allow the user to place default boot strings
on block 1 of the disk (2nd block), should the correct magic numbers be present.

If the correct options are used it will 'delete' the name used from block1,
thereby assuring that if the boot fails it won't be stuck in an infinite loop.

the boot strings are set by the utility "nextboot"
(not yet checked in, but being tested.)
By default these changes should have no effect on existing installations
and if compiled without the NAMEBLOCK option should be essentially identical
to the old ones.

0166c5c6b4 Allow specifying the BIOS drive number. Removed the hd drive type.
hd essentially wired the FreeBSD drive number to 0 without changing
the BIOS drive number.  Now the numbers can be specified independently.

Replaced the BOOT_HD compile time flag with with BOOT_HD_BIAS.  Defining
the new flag as 1 should give the same behaviour as defining the old
flag as anything.  I haven't tested defining these flags.

27253a3d9c Made the timeouts in gets() machine-independent. Use the BIOS tick
counter instead of the BIOS time call to save space.

Reworked the anti-noise timeout to avoid duplicating code.  The timeout
in the outer loop is now restarted after every noise timeout, so it is
now possible for the total timeout to be infinite; previously, the maximum
total timeout was 150000 seconds.

c50f3ecf5a Fixed restoring segment descriptors in prot_to_real(). The descriptors
must have limit 0xffff and attribute G = 0 (byte granularity) as well
as other properties that they already had (see e.g., the Intel i486
manual section 22.5).  Not restoring them broke Ctrl-Alt-Del in the
bootstrap for my ASUS P55TP4XE system, probably because the Award BIOS
does anti-tracing stuff involving inaccessible %esp's.

asm.S:
Don't use lret in prot_to_real().  This reduces the risk of using an
incompletely intialized stack segment and saves space.

While i've been at this, i've cleaned up some of the routines at the
end of i386/conf.c; all the importers of the latest CDROM drivers
forgot to fill in the appropriate information.  The `ata' driver
(vapourware?) does only occupy a slot in the bdevsw[] array, btw.

The actual import of the code does require a minor change in the SCSI
subsystem, and i want to have this reviewed by Peter first, so it will
be deferred for some days.  The driver is already working for me
though.

8da0f3b87a Make some functions static like they always should have been.
Change the interfaces of these functions to save space.  The code
that takes the least amount of space is often the opposite to what
you might expect.  E.g., it helps to waste a few bytes passing
pointers so that the compiler can't see that certain addresses
are identical (gcc likes to waste space by reloading fat constants
even when the constant is already in a register).

Rewrite getbootdev() to save 80 bytes of space and to make it less
ugly.  32 bytes were saved simply by omitting the continue statements
in the pseudo-switch.

a9ef92e638 Never pass char or short args to functions. This saves 64 bytes of
recently introduced bloat in just 2 calls to biosread(), although
very little in calls to putc() and serial_putc().  Gcc produces
amazingly bad code for unnecessary conversions.  E.g., if it has
`int x' in register %edx and wants to pass a char, then it could
simply push %edx and access only one byte in the callee.  Instead,
it sometimes unnecessarily spills %edx; it always sign extends
%edx and pushes the result.

Remove useless `extern' in function prototypes.

Remove unused declaration of `end'.

Declare pbzero() and pcpy() like the library bzero and bcopy().

Declare printf() properly.

9c6e0c69be . Make Poul's boot2 overflow warning less noisy in case the blocks
do fit, and beeping in case of an overflow.

.  Drop a comment about the ``FORCE_COMCONSOLE'' option into
   README.serial.

.  Increase the name buffer for the root directory from 100 bytes
   to 8 KB;  this is in no way ideal, but (IMHO) the best that can
   be done by now.  People did encounter problems with their root
   dir name listing overflowing the allocated buffer space.  Once
   we've got the three-stage boot, we should implement some basic
   malloc().  Swap space is already getting tight now, perhaps the
   swap should go into another 64 KB segment instead.

.  Make the keyboard probe less paranoid.  It should not give up in
   case of a keyboard that's continuously demanding RESEND's.  Even
   though the keyboard reset apparently has not been reported to be
   complete, it's at the very least proven that there IS something
   like a keyboard available.

   This solves problems with the ``Gateway-2000 AllKey programmable''
   (sp?) keyboard, that experienced a total hang with the previous
   probe.

the second stage boot is now 7152 bytes in size, just 8 bytes under
the wire. On the other hand, the new probe now does almost exactly
what syscons does, so hopefully this will do the trick. It seems

Christians README:
------------------

Hi Everybody!

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.

Make conditionals on BIOSWAIT consistent with usage in io.c.

If you had 'BOOTWAIT=0' in your /etc/make.conf then biosboot wouldn't
compile.  It was '#if' in io.c and '#ifdef' in probe_keyboard.c so I
changed the latter to '#if'.

Even if BOOTWAIT is undefined then '#if BOOTWAIT' becomes
'#if 0' so it should compile either way with this change.

b5d89ca8ad Load the kernel symbol table in the boot loader and not at compile time.
(Boot with the -D flag if you want symbols.)

Make it easier to extend `struct bootinfo' without losing either forwards
or backwards compatibility.

ddb_aout.c:
Get the symbol table from wherever the loader put it.
Nuke db_symtab[SYMTAB_SPACE].

boot.c:
Enable loading of symbols.  Align them on a page boundary.  Add printfs
about the symbol table sizes.
Pass the memory sizes to the kernel.
Fix initialization of `unit' (it got moved out of the loop).
Fix adding the bss size (it got moved inside an ifdef).
Initialize serial port when RB_SERIAL is toggled on.
Fix comments.
Clean up formatting of recently added code.

io.c:
Clean up formatting of recently added code.

netboot/main.c, machdep.c, wd.c:
Change names of bootinfo fields.

LINT:
Nuke SYMTAB_SPACE.
Fix comment about DODUMP.

Makefile.i386:
Nuke use of dbsym.
Exclude gcc symbols from kernel unless compiling with -g.
Remove unused macro.
Fix comments and formatting.

genassym.c:
Generate defines for some new bootinfo fields.  Change names of old ones.

locore.s:
Copy only the valid part of the `struct bootinfo' passed by the loader.
Reserve space for symbol table, if any.

machdep.c:
Check the memory sizes passed by the loader, if any.  Don't use them yet.

bootinfo.h:
Add a size field so that we can resolve some mismatches between the loader
bootinfo and the kernel boot info.  The version number is not so good for
this because of historical botches and because it's harder to maintain.
Add memory size and symbol table fields.  Change the names of everything.

Hacks to save a few bytes:

asm.S, boot.c, boot2.S:
Replace `ouraddr' by `(BOOTSEG << 4)'.

boot.c:
Don't statically initialize `loadflags' to 0.  Disable the "REDUNDANT"
code that skips the BIOS variables.  Eliminate `total'.  Combine some
more printfs.

boot.h, disk.c, io.c, table.c:
Move all statically initialzed data to table.c.

io.c:
Don't put the A20 gate bits in a variable.

Obtained from:
bios boot block changed to allow booting from both the attached graphics
display and from a serial port. (A specially compiled serial boot block
is no longer necessary.) The boot block should detect the presence or
absence of a keyboard: if there is no keyboard, COM1 is turned into the
console. This simulates the behavior of the Sun boot PROMs. Unplug your
keyboard, attach a terminal to COM1 and you should be ready to go. :)

e72e8750d3 Insert a hook to initialize the serial port at the beginning of
boot().  This is needed so the "serialboot" stuff can share this file,
too.

Everything is #ifdef'ed so it evaluates to nothing when actually been
built in the "biosboot" directory.

2c681fc102 This became a frequently requested item now.
The files in this directory are modified version of "biosboot".  The
only difference is in that they perform their I/O via a serial port,
so their preferrable usage is to form bootblocks for systems where the
kernel happens to have an "options COMCONSOLE".  Most of the code is
actually shared with "biosboot", and make will not (and should not)
descend into this directory by default.  It is in the responsibility
of the user to build these bootblocks instead of the original ones.

Subject: Mea culpa -- small fix for netboot fixes

In accordance with the unavoidable principle sof Murphy's Law, I discovered
that the fixes I recently contributed for the netboot code had some small
flaws in them. Two of them were just typos and had no effect on how the
program functioned. The other one was a missing line from the rootopts and
swapopts functions I created in bootmenu.c, which was supposed to initialize
the NFS sotype flag. It defaults to UDP, and you can change it to TCP with
the rootopts or swapopts commands, but then you can't change it back again.
I originally had a line at the top of each function to reinitialize this
flag, but somehow it got lost in the shuffle, probably because I don't
actually have a need for that flag yet.

68cbb04819 Many fixes from Bill Paul:
Smack the netboot program around so that it will allow the user to
  specify mount options.  [So that you can boot from a privileged port]

  Change the default boot image name in netboot to /kernel, then strip
  the leading slash when actually going out to get the NFS file handle.

  Added support for 3Com 3c503 cards. Also added another command to
  the (trans) that allows you to switch the 3Com's on-board transceiver
  on and off. (ether.c, ether.h, bootmenu.c)

  Modified the Makefile to support new compile-time options for 3c503
  cards:

  -DINCLUDE_3COM                Include support for 3c503
  -D_3COM_BASE=0x300            Define 3c503 base i/o address (if not
                                specified, 0x300 is the default)
  -D_3COM_USE_AUI               Disable the 3c503's transceiver by
                                default (without this flag the transceiver
                                is on by default)
