drochner ec191bc613 Fix operand size confusion in 16-bit code. 1997-06-13 13:32:09 +00:00
perry 00b5e61754 Provides "reboot" call, which just calles INT 19h to ask the bios to
reboot the machine.
This may be insufficient, but its enough for now.

perry 20b87fc0c9 1) Make carriage return start boot immediately.
2) Make "quit" reboot machine. This works by adding a reboot assembler
   hook that calls INT 19h

thorpej ecfdbcaa40 Mimmick the old boot block's hdN -> Xd0 (where X is specified by the
disklabel type) unit conversion behavior.

thorpej ddf4bc9113 Don't abort if we don't find an MBR or NetBSD MBR partition; simply assume
that the NetBSD portion of the disk begins at sector 0.

is 6c55a345c6 Make this compile with NetBSD-1.2D (if_ether.h location changed). 1997-03-20 16:15:15 +00:00
sommerfe 9fefd40478 In 16-bit mode, mov %ax,%bx is interpreted as mov %eax,%ebx; this
breaks zero-extension of the 16-bit memory size return from the BIOS.
on at least one system, the trash left in the upper half of %eax
causes the kernel to crash during VM system initialization when it
thinks it has on the order of 2**31 bytes of memory to play with.

We now *say* mov %eax,%ebx, but *mean* mov %ax,%bx..

perry 816bb96145 Initial import of new boot code, created by Matthias Drochner with a
little hacking by me. This isn't strictly identical to his 920312
release -- I've hacked it a bit -- but since we are taking over change
control it doesn't matter much.
