I'm trying to find a PCI based IDE controller that is Linux and ATAPI compatible, and handles at least UDMA-33.

I bought a job lot of Promise ATA-66 cards (PDC-20262 chipset) a while ago for this task,
only to discover that they don't work properly with ATAPI devices. Nor does the ATA-100 card (PDC-20267)

I opted for the ATA-66 cards over the older ATA-33 cards, because the ATA-66 cards (and newer) are flash upgradeable.
The older ATA-33 (PDC-20246) required a chip replacement.

I basically want a DVD-ROM and DVD-writer on seperate channels, without having to use up both on-board IDE interfaces.

There MUST be a PCI based IDE controller available that is fully ATAPI and UDMA-33 compliant.

Advice much appreciated

Investigate the controller in the nVidia ck804 chipset.

I have two IDE hard drives, and two optical drives connected to an ASUS K8N-DL mainboard with the CK804 chipset.
