You're problem almost certainly lies with the CD/DVD drive being on a
PATA (i.e. old fashioned IDE) interface which isn't recognised by the
Linux kernel. It boots using the BIOS and then can't see the CD to
continue.

Is this a problem with this specific motherboard/chipset? I ask because
I've never seen a CD/DVD which wasn't on an IDE interface. I'd have
thought that the IDE drivers would be able to find and use this device
unless the vendor has done something very strange with the chipset.

It's a problem specifically to do with the Jmicron SATA/PATA interface
which is used on many motherboards which have the Intel 965 chipset.
The Intel chipset doesn't have a PATA (i.e. old fashioned IDE)
interface at all so the JMicron chipset is added to provide a PATA
interface. The JMicron PATA interface doesn't have drivers in the
kernel except in the very latest (2.6.18) kernel. Ubuntu have patched
the drivers into the 2.6.17 kernel in Ubuntu 6.10 beta.


Also, I was considering this mobo for a new box, and this concerns me a
little... I was going to order it this afternoon so I'm glad I saw this
post this morning!

I've ordered a SATA DVD/CD drive to overcome the problem. The Intel
SATA interface works well with most reasonably new Linux kernels if
you turn AHCI on in the BIOS.
