On the P4 system, the CD would boot but hang.  None of the other systems 
would boot from the CD, so I think you're right.

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.
