ignore and set it to 18 sectors/track.  This allows FreeBSD to boot with

a80ddb7b20 First part of importing the Japanese `od' driver.
Claim the major numbers (before sombedoy else jumps in again and
claims the slots for his foocd driver :-), install all the hooks that
are required.

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.

c54e2295b7 Reset defaults in case of boot() is looping several times (e.g. the
user has entered a bogus kernel name in the first place).

Also fix the broken #ifdef FORCE_COMCONSOLE, it has been disabled by
accident.  (NB: the keyboard probe remains disabled however.)

Few cosmetic fixes (declare functions to be void instead of int),
while i've been at this.

serial_putchar() always hung if it was called and the serial port existed,
so booting with -h hung when the above bug was fixed.  Previously, setting
-h did nothing but -h was sometimes the default due to the stack garbage

79d93cb4f7 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.

bde
05efcad0fb 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.

96e572a290 . 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.

b759fab5af 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.

20571a3249 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.

453667f810 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.
