You could always hack your copy of the kernel's filesystem routines to do some-
thing like always use the negative of one of the essential paramters in the
filesystem, though changing over would be a nuisance.
But the best I've seen is something like my 5-5-91 AMI BIOS, which lets you
define the drive boot order a-c or c-a. Set passwording on changing setup,
set c to boot first, and as long as c is bootable a won't be checked to boot
off of. Unless they scribble on your hard drive's boot sector, it will always
boot to Linux...
