- ignore the partition table if it is identical with the bogus one in
/usr/src/sys/i386/boot/biosboot/start.S. Honoring the bogus size
field was fatal. The error is detected but other compatibilty
cruft weakens the error handling too much for this case.
- weaken the partition entry checking to allow the following treatments
of C/H/S addresses when C should be >= 1024:
(1) allow C = 1023, H = max, S = max.
(2) allow C to be correct modulo 1024.
Other compatibilty cruft weakens the error handling to allow all
C/H/S addresses, but there too many errors were reported.
Improve error messages:
- print C/H/S addresses if relevant.
- distinguish primary partition table from extended partition tables.
- don't use diskerr() except for i/o errors.

Two changes need to be made to allow 'config kernel swap generic' to
work properly without requiring any compile-time flags:
/usr/src/usr.sbin/config/mkswapconf.c: we need to define a dummy stub
for the setconf() function to replace the one in swapgeneric.c that
isn't available in non-generic configurations.
/usr/src/sys/i386/i386/autoconf.c: the -a boot flag causes setroot()
to be skipped and lets setconf() prompt the user for a root device.
If you skip setroot() in a non-generic kernel, you could get severely
hosed. To avoid this, we silently ignore the -a flag if rootdev != NODEV.
(rootdev is always initialized to NODEV in swapgeneric.c, so if
we find that rootdev is something other than NODEV, we know we're
not using a generic configuration.)
briefly over it, and see some serious architectural issues in this stuff.
On the other hand, I doubt that we will have any solution to these issues
before 2.1, so we might as well leave this in.
Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much
in the normal case.

Existing partitions on it work the same as in 2.0 except the

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.

message instead of relying on the fact that we are scheduled to send them.
The old method worked 99.9% of the time, but someone reported some periferals
that did MSG_REJECT at odd times (sometimes before we could send an SDTR
or WDTR) that we would construe as the response to an SDTR or WDTR message.
This also removes a possible race condition where after a bus reset (the
result of a command time out not during intial probe time), we might queue
two commands both requesting SDTR, WDTR or both.
