Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

Make sure the IDE hard drive is the master and the IDE CD drive is the slave. I had this problem recently where the bios refused to identify a hard drive if it was the slave to a CD drive. Reversing the order they were plugged in on the ribbon cable fixed the problem.
Jumper settings do matter, if both the optical drive and the hard drive are on the same channel (same ribbon cable), put the optical drive on the center connector and the hard drive on the end connector and set the jumpers to CS (cable select) on both drives. It is also possible that because all that was meant to go on the IDE channel was optical drives, DELL may have only included a 40 wire ribbon instead of an 80 wire which is recommended for modern IDE hard drives, check to see which one is included, this however, should not cause the bios not to see it.
Okay, this is strange. The conclusion I have drawn from the following is that BIOS doesn't like slaves :/
(hd=hard drive, od=optical drive)
With the jumpers on the od AND on the hd set to CS, I got the hd to MA when connecting it to the MA connector, but nothing on SL (although I, of course, connected the od to the SL connector). Switching their places, I got the od on MA and still nothing on SL.
Setting the hd jumpers to MA and the od jumpers to SL, then, gave me the hd as MA and nothing on SL, for both cable orders.
If that's the case, it's starting to sound like a software controller failure, which is part of the main chip set on the mother board. Meaning the chip set is hooped. Or some tracing got scratched or overheated on the mother board cutting off that connector. As far as the bios not reporting the information correctly, is a long shot, I would peg the chip set first. You can however, visit the computer manufacturer's web site or the mother board manufacturer's site (check computer vendor first), and see if there is a bios update available, most computers had one shortly after they were produced, they can usually tell you how to find what version is installed on the computer, and if the numbers are higher for the update, you might as well install (flash) it. Even if you have the latest, it might be worth flashing it again.
