BIOS not seeing CD-Rom, just hard drive

[Chris Tribiono]

Hi, I've been reading this group but can't find an answer to my issue.

Am hoping someone in here can help me out. I'm trying to get my machine
going for the first time using a new P5P800 motherboard, but I'm unable to.
The BIOS is only recognizing my new 300 gig hard drive if I don't have the
UDMA ribbon attached to the CD-Rom. Obviously I need to get the CD-ROM to be
recognized in BIOS in order to install Windows and everything else once I do
get running. I've got hard drive's UDMA ribbon coming from the Primary IDE
connector on the board ("cable select" jumper setting on the hard drive).
I've got the CD-ROM's UDMA ribbon coming from the Secondary IDE connector on
the board (also cable select jumper).

Any ideas as to what I'm doing wrong here? Is it possible that I have a dead
board? Any suggestions and feedback would be greatly appreciated!

Best regards!

I'm not really much of an expert, but in the many systems I've built,
the CD-ROMs don't work with the 80 connector UDMA cable. Instead, try
using the standard 40 connector cable.

Hope this helps.

Sounds like you have both the disk drive and CD drive set to Master. Double
check that the CD drive is set to slave, or hook the CD drive up to the
secondary IDE controller, which is a better way to do it anyway.

LOL CD-ROMs don't work on 80 wire connector. How funny is that? I build
computers as a buisness and have not used 40 wire connectors in years.

MY CD drives are connected with 80-wire connectors.
They work.

Well, he doesn't have EITHER of them jumpered as Master or Slave. He
said they're set to Cable Select.
So, my first troubleshooting step would be to put them on two
different IDE controllers, both jumpered as Master.

The only difference between the cables is 40 extra ground wires to
reduce crosstalk between the signal wires, thereby allowing faster data
transfers. Both types of cable use the same 40 pin connectors, so
there's no difference as far as attached devices are concerned.

Try setting master instead of cable select. Cable select doesn't work
with all IDE cables.
