Thanks, John. I didn't know what info would be useful, so I threw in the kitchen sink. I'll answer the questions below. On Monday 08 October 2001 11:24 am, you wrote:

I'd probably not use 2.4.10, it's got quite a few problems. Either 2.4.11-pre[45] or use the 2.4.10-acX kernels, they're more stable at this point.

Is it compiled into the kernel or is it modules?
I've tried it both ways. I was thinking of trying to build a Linux distro on my Zip drive so I could use the partition for my home directory. I can see the drive and fdisk it. When I try to do a mke2fs /dev/sdc4 the process hangs up when it tries to write out the accounting information.

What does dmesg say? Does it even see the device? Can you access the CDROM properly?
CDROM is working for playing audio and for reading data. I've installed cdrecord, and I can see the device when I do a scanbus /dev/sr0:1,1,0 so I think it's OK.
