Just tried a Celeron 600 system, with the same results. Whatever hardware the IDE/Adaptec floppy is expecting is not quite what it finds. The CD light does not even blink when it tries to "find the cdrom". UDMA disabled, 40-wire IDE cable, manually master/slave or different bus, none have made a difference. On the positive side, the floppy boots reliably.
