Demo problem - CDR drives not working

[MTUSUPPORT]

If it is a custom built system, do you know what the motherboard is? This is the actual board that the Processor (Pentium III) is plugged into, including every other card in the system.

If you don't k now, it may say on the board itself, so you might have to open the system up and read it off the motherboard.

This is what I think is needed to find out what drivers you can try to download to fix your problem. You have a problem with your system, that when you turned on the DMA the drives went away.

I am searching HP's website for this problem, to find the resolution.
