BIOS/Post startup not recognizing CD-ROM

[Rockhound]

Just recently bought a system to use as a server - Supermicro superserver 5033CT with a P4SCT+II mb installed, 3 ghz cpu, 1GB ECC ram, 2 SATA hard drives and a CDRW/DVD rom drive. Problem is the CD rom isn't always recognized during the BIOS/POST routine at boot time. Seems as if the BIOS keeps forgetting it. A second or even third reboot will usually cause it to snap back into shape and recognize it. Motherboard is an 875 chipset mb.

Now is this simply a power problem or possibly a bad battery for the CMOS? 350W PS currently installed.

Any ideas?

What brand PSU? Also, try switching what IDE channel it's on. If it's two seperate drives, then switch the drives around on the IDE cable.

I was having a problem like that with my harddrive when I put together my new computer. it turns out that my IDE cable went bad. I replaced it with an extra one I had lying around and to this day it has not given me any problems.

Don't know what brand PSU, will have to check. Could be the cable too, will have to try out another one to see. Thanks for the suggestion.
