Master/Slave CD-Rom - BIOS won't recognize

[Mitel]

I just finished putting together a new system (KT7-RAID, 900Mhz Thunderbird, 45G HDD) and have the following problem.

I have two new cd drives, a USADRIVE 52x and a IOMEGA 12/4/32 CD-RW. Both operate fine independently. However, when I connect them both up USADRIVE as Master and IOMEGA as Slave, the BIOS won't recognize any cd drive on my system.

I thought maybe the cable was bad, so I replaced it. I've checked and re-checked the BIOS, it's set to Auto detect IDE devices. I've checked the Master/Slave settings several times.

What am I missing?

Thanks,

Ben

Last resort, set both to CS (cable select) and see what happens..

You can also leave them set as None in the BIOS. They should work but you won't be able to BOOT from CD.

make sure you don't place the CD drives in the ata 100 controller ide channels.

I have a similar problem with my kt7-raid/tbird 900 setup.

I have a Cendyne Hitachi 12x DVD and a Lite-on 48x CD-ROM... the slave unit (the DVD drive) isn't there on bootup... when i go into the bio settings it magically appears.

Do you have a problem with the non-appearing drive when you get into your OS? Eventhough i don't see the drive on bootup, WinME detects it w/o problem.
