boot live cd or dvd with grub

This issue may be delt with on another thread but I could not find one.

Is it possible to add a cdrom or dvdrom to grub.conf so that I can select it and boot a live cd or dvd from a grub menu?

It looks like you booting the cdrom from the bios setting then selecting which OS to boot from there. That's cool but I'm trying to do the opposite.

It would be convienient if I could boot off the hard drive then select cdrom from the grub menu. It may not be possible but I would like to be able to put any live cd in the drive and boot it without having to change my bios boot order.

After some experimenting it appears that grub does not see the cdrom at all.

You may want to look into SBM (smart boot mgr)

This will allow you to boot from the CD, HD, FDD. I don't think you can boot to your HDD then go back and select to boot from CDROM after the fact. SBM will overide your bios boot settings.

Installed SBM onto a floppy. When the machine was Rebooted SBM came up and listed the cdrom. I had a knoppix 3.7 disk in the drive. When I attempted to boot the cdrom it returned "Disk Error".

Have you been able to boot cdrom with SBM?
