Sony CD-RW Problems

[Glenski3]

Can anybody help!

I have a Sony CD-RW CRX200E ATAPI Drive which does support CD+G...

I have now purchased a Sony CD-RW CRX220A1 Drive which does not support CD+G...

The problem I have Is that I want to run both CD-RW Units in my PC...

The CRX200E Is setup as the Master (IDE Secondary)
The CRX 220A1 Is setup as the Slave (IDE Secondary)

But when I come to reboot the PC It holts at the 'Verifying DMI Pool Data' and the whole PC freezes...

I have tried both drives around the other way regards Master/Slave... The settings in BIOS are set to Auto Detect!

Previously I had a standard Matsumi CD-Rom Drive running alongside the Sony CRX200E In harmony, with no problems...

It seems to me that both the Sony drives are In conflict with each other!!

Does anybody know what I'm doing wrong?

All cables are connected fine...
Is there something I need to do In setup?

Please help!

Cheers
