Thumbs down Hardware Change

I installed a new CDROM on IDE0 and moved my burner to IDE1, heres what it looks like...

Before :
HDD 20gig IDE-0 Master
CD-RW N/A IDE-0 Slave
None N/A IDE-1 Master
None N/A IDE-1 Slave

After :
HDD 20gig IDE-0 Master
CD-ROM N/A IDE-0 Slave
CD-RW N/A IDE-1 Master
None N/A IDE-1 Slave

My bios can read and boot off eather disk, but I don't know how to access the disk drive. "/dev/cdrom" doesn't seem to be anything,
bash-3.00$ lsdev

So how can I find out what names Linux has assigned my two CDROMs?

'dmesg | grep -i cd' should show you relevant information.

By the way, I would avoid placing optical drives and hard drives on the same ide channel when possible: optical drives run at ATA/33, forcing the whole bus down to ATA/33. But that's not related to your original question, just an observation.
