That's basically the same as every single bootloader ever, then. *All*
of them (other than WinNT's) use BIOS routines from start to end. (NT's
is ludicrously overdesigned and amounts to a small OS itself. Even it
uses the BIOS to load the second-stage loader, because you can't fit
a device driver into 400-odd bytes! And of course you must trust its
ordering if you use it.)

Aha, right. I long ago automated updating lilo.conf and rerunning lilo,
so I don't notice that anymore. :)
