1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

0c8ea4d48c Eliminated includes of the "temporary" backwards compatibility header
<sys/dir.h> in applications.  Maintained existing (inadequate) ifdefs
for dir.h vs dirent.h in libdialog, amd and rarpd, but didn't add any
new ones.

2e82980a4c Moved instantiation of `poff' to sys.c. It is no longer used in disk.c.
Saved a few bytes by copying `dosdev' and/or `name' to local variables.
This optimization (for dosdev) was done in one place before but this
was lost in the devread() cleanup.   This optimization (for dosdev)
can almost be done by bogusly declaring dosdev as const, but gcc still
often space-pessimizes code like the following:

	extern const int dosdev; ... foo(dosdev); bar(dosdev);

gcc often doesn't bother to copy dosdev to a temporary local because
the local would have to be preserved in memory across the call to
foo().  OTOH, for

	extern int dosdev; ... auto int dosdev_copy = dosdev; ...
		foo(dosdev_copy); bar(dosdev_copy);

the copy must be made because foo() might alter dosdev.

980b7c9573 Rather than adding more gunk here, clean some of it up:
devread() had a bogus interface, cleaned up.
	Bread() did an unneeded bcopy(), don't.
Saves 80 bytes and some time.

6074a34497 Saved 48 bytes (46 before padding) using assorted nano-optimizations:
- avoiding strcmp("?" saved 12 bytes.  gcc inlined the strcmp()
  but this takes as much or more code as a function call.  The
  inlining was bogus because the strcmp() in the bootstrap isn't
  standard.

- using a char instead of an int for the boolean `last_only' saved 8
  bytes.  Booleans should usually be represented as chars on the i386.

- simplifying the return tests saved 9 bytes.

- using putc instead of printf to print a newline saved 3 bytes of code
  and 2 bytes of const data.

- avoiding `else's by always doing the else clause and fixing it up
  saved 4+8 bytes.

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.

0f72d204e6 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.

Pointed out by: wosch@cs.tu-berlin.de (Wolfram Schneider), for the init bug

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.

3dea9c24ac Improved the user interface:
1) Added file list capability via '?'.
2) Arranged usage info to be more unix-like.
3) Fixed backspace over prompt annoyance.

b95ed23990 Fixed bootblocks to work with FreeBSD 2.0
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
   is set to 64K which is too big for the bootblocks to deal with.

dd05fde699 Removed all patch kit headers, sccsid and rcsid strings, put $Id$ in, some
minor cleanup.  Added $Id$ to files that did not have any version info, etc

f7710986e2 New boot blocks, from Bruce Evans, and NetBSD fixes. Allows kernel to
be loaded above 1MB.  Same boot code for floppies now.  Speed improvements.
etc etc etc. (I don't have much history on this, but then have been tested)
