Don't know.  I installed this system with a CD-ROM drive on an old
motherboard.  Then I got the DVD Writer and added it.  Then I swapped
motherboards.  Then I removed the CD-ROM.  All this happened over a 3
year period and each change was 6-12 moths after the previous.  I was
just wondering if the Plextor PX-716A was SUPPOSED to be bootable, or
can FC5 boot off it, or do I need to go buy a CDROM just to boot off CD?
