Yes, sure, I'd set the CD to slave mode though the jumper. As I said, the BIOS also detected it accordingly. ----- Original Message ----- From: "AMD 950" <[log in to unmask]> Sent: Wednesday, December 26, 2001 12:46 AM Subject: Re: CD doesn't work as slave Did you check the jumper opn the cdrom. They can be jumpered as Master, Slave Or Cable Select. My guess is your new drive is set to Master. This explains why it works on an IDE channel by itself but not when sharing a channel with other device (your main HD will always be Master) Cerry Mistmas Ian Carmichael ----- Original Message ----- From: Bharat Ale . The new CD drive was Samsung 52x. I connected this CD drive in place of the old one - slave with master HDD on IDE1. Now this CD drive is detected alright by the BIOS but doesn't come up in Windows 98 - its as if its not there. Now I connect the CD-drive to a separate IDE cable (IDE2) and its fine.
