But anyway, what are the requirements for a DVD drive to be bootable for an old Mac? Does it require a drive with all 3 jumper settings? (Master, slave, cable select). Just curious in case anybody knows....
There is something about the drive that makes it bootable (seen by the Mac's ROM or firmware without the need for any additional drivers or software), and the manufacturer needs to set it that way.
Apple isn't alone in this, for years systems like Apples, NeXTs, Suns and SGIs required CD drives that were bootable... and oddly enough, the same drives that are bootable on my Suns and SGIs are also bootable on my Macs.
But that is why going to a Mac outlet is better than going to a PC out let for something like this. And you really don't need "new". Just grab an old used Apple DVD drive. People are usually replacing them with drives that do more, so you can get a DVD drive pretty cheep.
Mine was pulled from an old Blue & White G3 that moved up to a DVD/CDRW drive.
As for the settings, you'll note that your logic board as two internal ATA buses and one internal SCSI bus. One of the ATA buses is dedicated to just the CD drive. It is that bus that you need to put the DVD drive on (set to Master or cable select... I'll have to check on that). If you get an Ultra ATA card, then you can add other things to the second ATA bus on the logic board.
On my system I have the original CD drive on the first bus and the DVD drive on the second, the hard drive is on an Ultra ATA/66 card (which has two buses allowing for four drives).
