Can't detect DVD-ROM

[Washington]

I have a Pioneer DVD106S drive and an Abit KT7A motherboard. My problem is that the BIOS sometimes does not detect the drive at boot-up. I have tried EVERYTHING to get it to detect reliably (latest BIOS, new cables -80 way or 40-way, master/slave settings, VIA chipset drivers, tried both IDE channels, re-installed operating system etc) but no luck. When it is found it works perfectly. This is an ATA66 drive and I have heard that it does not like being on a shared IDE channel or being used with 40 way cables. But I am not doing this and still detection fails. Someone has mentioned detection failure might be to do with the power supply - a have a good 300W power supply fitted but this seems the only thing left that could be wrong. Unless the drive has a fault but I don't think it has. Any other ideas much appreciated - this is very frustrating as its a superb drive.

Try setting BIOS main setting to "auto detect" for that drive position.

What's the frequency, Kenneth?

Already tried, also tried setting IDE device to "none" but makes no difference. I should also mention that I have a Yamaha CD writer which is always detected and I have also used a Liteon drive in the past which also gave no problems. It's just the Pioneer that my computer does not like.
