5f0539ec6c Saved a few bytes by omitting frame pointers, using byte-sized
instructions more (many cases were already intended to be byte-sized
but were missing prefixes so gas assembled them bogusly), and
rearranging a loop to test at the end.

de2cf96615 - Added support for "dual" internal/serial consoles (-D flag). If -D is set,
then all i/o from the boot blocks is to and from both the internal console
  and the serial console.  -D has no effect on the kernel (-h decides the
  kernel serial console as usual).  -D should normally be set in /boot.config.
- Get help messages from /boot.help.  You should copy boot.help from the
  biosboot directory to the root directory on the boot drive when you
  install new boot blocks.
- New, less invasive keyboard probe.  Enable keyboard probe dynamically (-P
  flag).  Should probably never be used (use -h instead).
- Fixed/improved initialization from boot.config.  It didn't interact correctly
  with the NAMEBLOCK option, and the initialization of the drive/unit/partition
  didn't stick when a non-default kernel name was entered.
- Don't reset or forget the default drive/unit/... or kernel name so often.
- Set the default kernel name to something unbootable after `?'.
- Display the defaults better.
- Removed PROBE_KEYBOARD_LOCK option (use -h instead).,
- Removed BOOT_FORCE_COMCONSOLE option (use device flag 0x20 instead).
- Removed -a (RB_HALT) flag.  This flag is only used for reboots.

906265bada Removed some useless code:
- gcc assumes that %ecx and %edx are clobbered (due to calling
  conventions), thus there is no need for saving/restoring those two
  registers.
- %es is reset to default value by real_to_prot, thus there is no need
  for saving/restorig that register.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

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.

6564e095d3 Rationalize support for serial consoles running at baud rates other than 9600
baud.  This isn't particularly beautiful, but neither is it disgustingly
gross.

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. :)
