23fd5d0d9b #if -> #ifdef, fixes XMS support 
from Martin Husemann, pr port-i386/3941

bdb232d2b6 Don't use <lib/libsa/if_ether.h> anymore. This was a copy of the 
old (before ARP changes) <netinet/if_ether.h>, intended for
temporary use.

6b02672ee8 Cleanup include file usage: Avoid user space headers, use 
<sys/types.h> instead of <sys/param.h> where possible.

e19d907613 Support SMC Ultra. 
The code is becoming messy...

faf30015a9 Support 3c900 Combo. 
(The elink3 code works probably with other boards too, but this is what
I tested.)

cc7a41e5d2 Weaken the restrictions on the device file name a bit: /boot can 
now be installed on any partition.
Allow PRIM_LOADSZ to be set in the Makefile.
This together allows to make bootable 720k floppys.
closes PR port-i386/3751

a0d9d3bc54 Allow to boot from DOS if a XMS manager is installed. 
XMS is recognized and used as temporary buffer for the kernel image.
The processor must still be in real mode at program start, so EMM386
or QEMM are not allowed. W*95 is OK.
Written by Martin Husemann (pr port-i386/3336).
Completely separated from other bootloaders for sanity.

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.

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

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.

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..

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.
