Oh yes, that's a Catch-22... but if you configure it out in the setup,
and the machine does boot from a floppy, you can still run some disk
utilities (maybe Speedstore or Norton? I don't know them exactly) on
the disk, if they don't care about the BIOS setup. (Some partitioning
uitilities - does anyone know better? - bypass the BIOS configuration
intentionally to enable the use of uncommon disks.) It should be
possible to at least write a clean master boot record to the disk,
enabling the machine to boot up with the disk configured in correctly.

Good for you; if someone had really replaced the BIOS you would not
be likely to get the machine working unless you caught him...

O.K., 'most likely' sounds much better. :-)
