New issue. My DVD drive is no longer detected in My Computer. BIOS detects it. I tried removing the upper and lower filters registry entries and restarting, but still no DVD drive icon in My Computer.

See if it is detected if a disc is in the drive when the PC boots. Is it a SATA or ATAPI DVD drive?

I can boot from a CD or DVD. It's ATAPI. In addition to deleting the LowerFilters registry entry, I ran the Microsoft CD and DVD Fix It tool, which didn't help. The DVD drive isn't shown in Device Manager by default. It's shown as a ghosted icon under hidden devices that's disconnected. All drive jumpers and cables are correct and secure. The drive is also not shown in Computer Management. The DVD drive is healthy. No idea what to do.

You must screw with your OS quite a bit to mess that (DVD) up!

Now for the Rear Sound - as I remember, there's some PINS on the HEADER that goes to the FRONT PANEL that you MUST JUMPER if you are NOT plugging in the FRONT PANEL. Remember me saying something about "plug into FP and Rear Is Disabled? Look back at the links I gave - the info as to WHICH "pairs" is clearly given. That's all I'm going to say - YOU do some footwork from what's given.

No, I hardly screw with my OS. The DVD burner disappeared in Windows after I transferred the system into my new case and removed the CD-ROM drive and card reader to regain some power supply wattage so I could install a front fan to improve cooling.

I know that. I was ready to buy two jumpers to do that. If I were to attach the case front panel audio connector AC'97 audio to my motherboard's front audio header and if a pin was wrong, is there any chance of damaging my motherboard, or would something just not work?

However, my system has no sound from the analog desktop speakers connected to the rear green output port. I thought the AC'97 audio case front panel connector was for only front panel audio?

You just now said "OHHH!!! I forgot to mention, I realize the problem - scratch that one", otherwise I wouldn't have mentioned it.

You ALSO didn't mention that! We do NOT consult "crystal balls" here. Try this - go into SAFE mode and REMOVE those items from the Device Manager and REBOOT! I "assume" you set the jumpers on the back correctly?

I didn't think it was necessary. I mean, it's just a CD-ROM drive and USB card reader. I uninstalled the DVD burner, CD-ROM drive, and USB card reader in Safe Mode in Device Manager, but Windows never said it found new hardware after I logged back in and scanning for hardware changes did nothing. As far as I know, the drives' jumpers are correct. The WD hard disk is set as Master w/ slave present and the DVD drive is set as slave.

1 - Have you "assigned" ("stuck") a Drive Letter to ANYTHING AT ALL?
2 - Look in "Computer Management->Removable Storage" and see if anything is "stuck"
3 - Look in Registry "HKLM->System->MountedDevices" and see if the old DriveLetters are "stuck"
4 - Does the BIOS (F1 ?) have the Secondary (DVD Drive) on "Auto"?

Not the live system, but when on UPS it would cause an overload, so the CD-ROM drive, which uses about 25 W, and the USB card reader, which uses about 5 W, had to go.

The only device that has a drive letter is the primary active system partition, with drive letter C:. As I said earlier, the DVD burner doesn't appear in Windows, so I can't assign it a new drive letter in Disk Management.

I suspect this has something to do with the IDE cables and jumpers. Even though they're correct, the BIOS doesn't seem to like many configurations. Here's what I've tried so far, and all IDE cables are good:

Single cable = IDE cable with 2 connectors
Double cable = IDE cable with 3 connectors

Single cable set to CS and single cable set to CS; no BIOS detection.
Single cable set to M and single cable set to M; no BIOS detection.
Single cable set to M and single cable set to CS; no BIOS detection.
Double cable set to CS and CS; Windows won't boot.

I have three more cable configurations to test.

The DVD burner isn't detected in Removable Storage. Remember, Windows isn't detecting the DVD burner, so nowhere will it be found in Windows.

Deleting the unused drive letters under HKLM > SYSTEM > MountedDevices did no good.

The BIOS does detect the DVD burner as Channel 0 Device 1 on auto.

I NEVER use CS at, at any time, on any cable, an any connector, on any device, ever.

I manually jumper the devices to Master and Slave, and connect only to 80-pin IDE cables. Assuming your motherboard has two IDE connectors, it shouldn't make any difference whether you connect your HDD "C" and your DVD both as Master on separate cables connected to your motherboard, or if you connect your HDD "C" as Master and your DVD as Slave on the same cable, but you could try it both ways. In both cases, swap the motherboard connectors you use and see if that makes a difference, but the HDD "should" be connected to the IDE motherboard connector with the lowest number, 0 or 1, depending on how your motherboard is marked. In all cases check if the BIOS is picking up the devices correctly or not. If not, it is extraordinarily doubtful, if not impossible, that Windows will be able to do any better. If the BIOS is not picking things up right, if possible, plug the cables and HDD or DVD into another computer and verify it is picked up correctly there. If the other computer picks it up right, then the problem is on your motherboard or in a BIOS setting. (If it is able to disable an IDE channel perhaps, I'm just guessing here.) If the other computer does not pick it up right, I'd bet it is the cable. Try swapping the cables from the HDD to the DVD to confirm. You should also look very carefully at the connectors on the back of the DVD and on the motherboard to make sure that in your plugging and unplugging that you didn't bend a pin by mistake. It's happened. The connectors should all have either 39 or 40 pins. The only one that should/can be missing is pin 20 which is sometimes used as a key. See - http://en.wikipedia....ki/Parallel_ATA That's all I've got for now.

None of those are the problem. As funny as it sounds, I bet if I use the original OEM IDE cable setup of one master cable for the hard disk on channel 0 and the other master and slave cable on channel 1, the DVD drive will be detected by Windows. I've never heard of Windows being so picky about IDE cables before, but I just have a feeling this will solve it. I don't know why, but I just know it probably will.

That sounds like one of the arrangements I suggested. How were you trying to connect it that didn't work? What was different?

And what did this mean anyway, just out of curiosity? (I don't know what "upper and lower filters registry entries" are.)

These have something to do with optical drives and sometimes deleting them restores the optical drive icons in My Computer, but not for me.

Has anyone ever heard of an OEM BIOS requiring a certain IDE cable setup, or it will cause these kinds of issues? That's the only thing it could be.

80 wire cables are colour coded, you cannot "invent" a master or slave, if the connector is gray, it is for a slave device, if it is black it is for a master device, the blue ONLY goes to the motherboard and still using cable select is NOT recommended (by me).

Because they tend to NEVER work properly/because it's not just your motherboard IDE ports (or BIOS) that are particularly fussy.
Thus DO NOT use Cable Select, in most cases it resolves to a vain attempt.
