Board: Gigabyte 965P-DS3 (rev 2.0)
DVD drive: NEC ND-3500AG

Symptom: "Can't find KNOPPIX filesystem, sorry". I've tried all combinations of the "all-generic-ide" and "pci=nommconf" cheatcodes with no help (though all-generic ide causes me to see an entry about enabling DMA for my DVD drive). using "expert all-generic-ide pci=nommconf testcd", I see that it properly detects my DVD drive as hdi (the SATA drives show up as hda and hdc), and identifies it as an ATAPI drive and the NEC model number is correct.

I've tested this CD in another machine with this DVD drive -- the disk and drive are good.

Any thoughts on what I can try? I'm using KNOPPIX_V5.0.1CD-2006-06-01-EN. Would a SATA CD drive work better?

Thanks in advance for the help,

Jonathan
