Unlike in an i386 a.out assembler, where in an .align n directive n is meant
...
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.
Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.

Make this compile and work again after the assembler update.
...
The new assembler doesn't allow 16-bit relocations involving arithmetics
with 32-bit variables. (The old one did silently truncate, which was
the right thing in our case.) Further, the new assembler uses to scatter
size prefixes around if the size of the operation is not explicitely
specified, even if the result is nonsense, eg for moves to segment
registers or control registers.
Add some debugging code (generating printouts) and comments.
Remove the !BOOTROM code which was intended for a DOS harness but isn't
that useful anymore.

wpaul 1998/07/02 08:36:36 PDT
Modified files:
sys/i386/boot/biosboot start.S
Log:
Add workaround to allow the FreeBSD boot block to work on
Kapok Computer Co. notebook with AMI 'WinBIOS' which seems to insist
on having a short jump and nop as the first instructions in the
boot sector code. The prevailing theory is that the BIOS is doing
some sort of boot sector virus detection and refusing to run any
boot block that doesn't start with the same instruction sequence as
MS-DOG boot sector code. If this is the case, it would be nice if it
actually printed an error message to this effect instead of just
saying 'FAILED.'
This workaround has no effect on the boot sector code other than to
increase its size by three bytes.
