As you will see, I haven't a clue.

When installing RH8.0 and using Grub, I told the installer to pass hdc=ide-scsi hdd=ide-scsi to the kernel. hdc is a DVD-ROM and hdd is a CD/RW. Now the DVD drive only reads CDs.

Should ide-scsi emulation only be used for devices that are RW and not for readers only?

If need to remove the emulation for the DVD reader, how do I do it? grub.config is not the place but, for the life of me, I can't figure out what I need to edit. With grub as the booter, where is the stuff that would be in lilo.config?

well you just simply remove the hdX=ide-scsi section in grub, that's all there is to it.

You won't believe how many times I looked at /etc/grub.conf with out seeing the ide-scsi stuff. Thanks, acid_kewpie.

Turns out that that was not the problem. I have been running various versions of Red Hat on that machine for a couple of years and both optical drives always have automounted when non-blank media was inserted. My problem was that for some reason and have to manually mount the DVD drive. The entries for both drives have the same parameters in /etc/fstab.

BTW, the DVD seems to be faster with scsi emulation enable.

Are you booting from the drive? If you are not using GRUB, probably you are using LILO. Check the file /etc/lilo.conf.

I use ide-scsi for both my DVD and CDRW, (hdc and hdd), and I've found that creating a /dev/dvd symlink helps.
