bios does not recognize optical drive

by Dan J S / October 14, 2005 9:43 AM PDT

Here is my problem.I went to upgrade to a new motherboard,a Gigabyte GA-8PE1000PRO.Bios recognizes my hard drives and zip drive, but does not see or recognize my Optorite DD-0203 drive.This drive works fine with my older motherboard, a Gigabyte GA-8SQ800.I did try new cable and confirmed the jumper positions on the drive.I flashed the bios to the latest version also.Older optical drives are recgnized on this new motherboard. Any ideas here?

I thought of trying this. However, Optorite does not show an update for my model,drivers.com does.This makes me a little uneasy.The drive itself is great with the old motherboard.I gues I have nothing to lose at this point. Thank you very much for the suggestion.

You did say that the BIOS (not Windows) doesn't recognize the drive. I wasn't careful in my reading of your original posting.

I think Krazyken44 is on the right track. I have had drives that don't work well with other drives on the same IDE channel (same cable). See what happens when you try different postions. Does the drive work by itself as a master or cable select device?

(NT) HMMM, Similar problem

I've this same problem some BIOS's will not see a optical drive unless its on an 80 pin IDE wire.
This is due to the UDMA transfer rate. You can set this in BIOS to run PIO or slower transfer rate. You can also turn of the 80pin detect in BIOS.
This is hard to explain why, so look at the wire if it's thicker in the strands than some of the other IDE cables if it is its 40pin change it to 80 pin.
Also, some I own a zip drive they can cause problems if on the same cable. I had to take mine out.
You may be out of luck some things in a computer hardware just don't play nice, so good luck.

First of all, thank you for all the responses and helpful suggestions. After flashing the firmware of the dvd unit,the bis would recognize it ONLY as a secondary IDE slave, and only with the older thicker IDE cable.I set up to install the OS and the bios quit recognizing the optical drive again. In fact, it stopped recognizing the older optical drives it once did. I cleared and reflashed the bios in case of any corruption issues. No help and I have concluded the motherboard itself has some serious issues. I will replace it when budget allows. Thank you again!
