I could really use a pointer or two...

I'm still playing with Assembly stuff, staring at all of the .S files
I encouhter while trying to compile the Sun3 boot loader for i386. It
appears that there's 2 sections of the bootloader in M68k ASM,
ctrlsp.S, and SRT0.S. locore.s is also present, but not used in the
bootloader. What do these files do? Do I need to write a functional
equivilent for x86 ASM? Was the Sun3 bootloader written completely
from scratch?

I commented everything out of SRT0.S jst to get it to compile, in
anticipation of linker errors in the future.

Thanks!
