What device is master? It is technically not valid under the IDE specs
to have a slave without a master and it doesn't have to work properly.
Any idea which type of IDE controller it is? Perhaps lspci could list
something useful.

That uses El Torito emulation from the BIOS. The kernel does native
access (since the BIOS can't be used once you switch to 32 or 64bit
mode).

If it works with the BIOS for booting, then it must be a working DVD
drive and a working IDE controller. Or at least one would think so.
If you have the system running, capture the output of 'dmesg' and post
that. Maybe someone will notice something that explains the problem.
