 Some Dell notebooks do this, IIRC.  Try removing the HD from a Latitude
CPi or CPiA and then booting from a floppy distro like tomsrtbt (from
www.toms.net). It's been a while but that 20808 number looks awfully
familiar...

My Latitude CPiA does not exhibit this, both with a rather old BIOS
and with the newest BIOS.  I'd appreciate hearing of other systems
that do though.  If it's a common occurance, I should be able to deal
with that as a special case.

Thanks,
Matt
