The board prompts me, how, exactly? Note that the boot sector on this
laptop's hard drive was put there by Grub so I can boot Linux.. This
limits the interaction options a bit. Also, note that the people who
have suggested boot-sector programs that prompt have forgotten that
some computers have non-boot drives...

I do believe this is implemented totally in the BIOS, the same way the
BIOS password itself is implemented. You don't enter the right password,
the BIOS routes the disk's IRQ to Zimbabwe. ;)
