I think the original poster was looking for a solution so that he
does NOT have to TYPE hd(1,a)/kernel each time on boot.
The solution is not in changing the kernel, but the boot blocks
of the floppy or sd0 drive that is being booted from.
% cd /sys/i386/boot/biosboot
% vi boot.c
part = 0;
unit = 1; <-- Change unit and major. With my hardware config
maj = 1; <-- this boots from hd(1,a). Your numbers may vary. Play around.
% make
% disklabel -B -b boot1 -s boot2 sd0 # installs the bootstrap code on sd0
use fd0 instead of sd0 when you want to change the code on a boot floppy,
so that the kernel is loaded from hd(1,a).
Bye, Jens
