at the next syscall or non-FPU trap, if any. It hung the system for
a test process that masked SIGFPE's and divided by zero. The faulting
division was returned to endlessly and this gave plently of opportunities
for the swi_ast_phantom case to be reached; after it was reached the
system hung because the ASTs for preemption and SIGINT handling were
disabled.
just thinking about it.
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.

Slice 0 is now for the first BSD slice. The first BSD slice is
the first DOSpartition with id 0xa5 or the whole disk if their
are no DOSpartitions (except the latter is not yet implemented).
Existing partitions on it work the same as in 2.0 except the
'd' partition is no longer special and partitions are relative

Slice 1 is now for the whole disk and gets a read-only label
describing the disk. Previously, slice 0 was for the whole disk

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.

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.

Reorganized some of the expressions for efficiency.
Fixed the new pmap_prefault() routine - it would sometimes pick up the

was paged out. The routine remains unused and commented out, however.
Explicitly free zero reference count page tables (rather than waiting

raw things (what hardware do for us, exactly) as default case,
all driver features must be _optional_. Modern VGAs have internal
configuration utilities to set cursor shape/blinking which stored

by forcing software cursor. Moreover, software cursor is hard
