the bios

if hda is not found, it will go to hdb, than to hdc or whatever
you set in the bio

you should use a boot order of: fd->cdrom->hda->hdc->hdb->hdd ...
	- some bios tries to get fancy and call it hd0, hd1, first drive,
	second drive, third drive, and other whacky names to confuse us

- not sure, but maybe it just boots from the drive the responded faster ??

probably because you didnt install a proper "boot sector" info onto hda

i suspect you can copy the boot info from hdb onto hda and it will
start booting from hda, except the other choice could be neither will boot
afterward .. :-0
	- so make sure you can boot off floppy and cdrom before playing
	with boot info ( lilo, grub, syslinux, loadlin, ... )
