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.

   Thanks goes to Scott Blachowicz <scott@statsci.com> for his
   extensive testing of my various interim (debugging) bootblocks
   to get this working.

15c99149f8 Boot block cleanup.
o Fix the keyboard probe to properly wait for the ready bit before
sending a command to the keyboard controller.  This should avoid the
problems some people are experiencing where the boot blocks hang the
system during keyboard probe.  (It does solve it for me.)

o Fix a bug that effectively prevented the boot blocks from ever
passing control to the serial console.  [while(--retries) instead of
while(retries--)]

o Gratuitously reduced the keyboard probe timeout from 500 to 5
seconds. :)

o Introduced a new option ``FORCE_COMCONSOLE'' as a commented-out
example in the Makefile, to force the usage of a serial console
regardless of a keyboard being connected or not.

o Moved all external declarations to boot.h, declared all functions
there, and ANSIfied all function declarations/definitions.
(printf() remains bogus, however -- i'm too lazy to fix this.)
We're in the ninetees, dunno why we should still support compilers
from the 70's.

8a03631b28 According to a Usenet posting forward to me by Jordan, there's
at least one user out there who's system won't autoboot from the
serial console because of what sounds like 'phantom keystrokes'
making the timeout timer trip. I've tried to solve this by
adding an extra call to init_serial() right before the 'Boot:'
prompt is printed (done only if RB_SERIAL is set) to hopefully
make sure that the input buffer is clear. Unfortunately, the fellow
is in Germany and I haven't heard back from him yet. I haven't
been able to duplicate this problem on my hardware, so this is
a stab in the dark. At the very least, it shouldn't hurt anything.

e8dfeb8828 Some people have complained that they were unable to boot the
Feb. 10th snapshot. The keyboard probe in the bootblock seems to
have been singled out as the cause of these problems, so I've beefed it
up alittle. This pushes us right up to the edge of the size limit:
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
to work properly on my hardware, but then so did the old probe.

b8e4cd2bb3 This is a MS-DOS program, but is does something useful for us:
It boots FreeBSD from a running MS-DOS system.

It's compiled using some MS-DOS tools, but there is a binary
hidden in the uuencoded file.  (Go ahead, flame me if you can come up
with a solution for the problem.  Just saying "this is bad" doesn't count!)

Rod, you were right: one would have to deal with weird interfaces to the
memory managers, and it seems that Christian found them all, and made them
work.

Thanks Christian!

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.

netboot/main.c, machdep.c, wd.c:

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. :)

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.

9b1096e759 From: wpaul@ctr.columbia.edu (Bill Paul)
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.

    the top of this segment.  This corrects the problems machines with 512K
    base memory had booting.

2.  startprog routing rewritten to convert the BOOTSEG ss to a KERNELSEG
    ss, this eliminated the last of the >512K memory references.  Additional
    cleanup in here included a better way to copy the arguments to the
    kernel stack.

3.  Elimination of argv and esym cruft saved a few bytes.

4.  Only need to truncate the head.a_entry to a meg boundary once intead
    of every time we used it!  [Saving more bytes].

5.  Addition of version 1 bootinfo structure support.  These boot blocks
    pass the kernel name in to the kernel now.

6.  Removed historical comments about MACH argv stuff, as it is useless now.

12fafb2d5a 1. Completely rewritten Makefile that uses bsd.prog.mk more effectively.
2.  Clean up the .S files to use /* */ style comments.

This is a totally cosmetic change, not one byte of the resulting boot
code changes.  But at least it is installed with correct owners and in
the right places, and gets recompiled correctly when things change!

1) Fixed up some header locations
2) Replaced list of boot files with /kernel
3) Changed disklabel use in Makefile to conform to 4.4
4) Added size command in Makefile to get close estimate of bootblock
   sizes. Total size of text and data must be below 64K, slightly
   overestimated since a.out header subsequently gets stripped.
5) Various buffer sizes are set to 8192 bytes in sys.c. In 4.4 MAXBSIZE

1c28e35f68 Commit a whole cluster of last minute critical (and one cosmetic) fixes
from David Greenman, Bruce Evans and Julian Elischer.

They are:

[vnode pager - David/Bruce]:
  The following patch fixes a problem where some data could be lost in a
delayed-write buffer if the cached buffer was larger than a page. This fix was
provided by Bruce Evans and modified slightly by me.

[st.c - Julian]:
  My fix for "bad request, must be between 0 and 0"

RTFS if you're interested).

[gnu/fpemul - David/Bruce]:
  These changes fix single stepping of emulated FPU instructions.
Previously, the instruction after an emulated instruction was
executed without causing a SIGTRAP ...

The also fix the initial control word being different for the
GPL emulator (it is still wrong for the old emulator) and remove
an unnecessary panic when emulation is not configured (I hope at
least init, sh and reboot will run without floating point.  I
remember only df and mkfs being broken by the lack of FP in 0.0).

[Various fixes described below - Bruce/David]:
sys/i386/boot/boot2.S:
        Yet another attempt to propagate the correct fix for 16 vs
        32-bit mode bugs.  [verified]

sys/i386/i386/db_interface.c:
        Protect against reentering Debugger().

sys/kern/kern_time.c:
        Don't allow 'time.tv_usec == 0' except at clock interrupts.

sys/pcfs/pcfs_fat.c:
        Make it compile without -O.

sys/scsi/sd.c:
        Fix as posted to some freebsd mailing list.
        (changes the order of the assignment of "sectors" because it earlier
          value is needed first -DG)

sys/vm/vm_glue.c:
        Fix stale comments and verbose code.

sys/vm/vm_mmap.c
        Fix off by 1 errors and verbose code.

[From Nate - cosmetic but non-intrusive and useful enough to go in]
sys/i386/isa/isa.c:

>From: bde@kralizec.zeta.org.au (Bruce Evans)
Subject: cache botch in bootstrap
Date: Sun, 20 Feb 94 18:14:35 +1100
The cache in the bootstrap loader didn't allow for the device changing.

This caused surprisingly little trouble - the cache is only for a single
track (or part of a track), and the first access to a new device is
always for an early sector, so there is no problem unless the last access
to the old device was for an early sector.  I saw the problem on a system
with BSD on wd1 and no label on wd0.  Everything worked if the the device
name wd(1,a) was specified before the default of wd(0,a) was tried, but
when the default was tried, it failed on the first sector because there
was no label, and then the first sector on wd0 was always used instead
of the first sector on wd1, so there was apparently no label on wd1
either.
