I bought a new motherboard (Gigabyte GA-P35-DS3R)) and found that my IDE cdrom/cdrw/dvd/dvdrw drive (LITE-ON DVDRW SOHW-832S) would not work. The main symptom was a lack of appropriate devices showing up in my /dev directory.

This motherboard uses a chip that Gigabyte refers to as a Gigabyte SATA2 chip. However the underlying chip appears to be a JMicron 20360/20363. The major tip to getting my setup working is that fact that the IDE devices plugged into this chip are treated as SCSI devices. Thus it was necessary to enable support for SCSI cdroms. (Device Drivers->SCSI device support->SCSI cdroms).

I believe this is because the chip is really a IDE to SATA2 converter, as opposed to a raw IDE device.

[edit]

More Details

Do:

  1. Check the bios. You should set the JMicron chip to run in AHCI mode, not IDE.
  2. You need to enable SCSI cdroms. (Device Drivers->SCSI device support->SCSI cdroms)
  3. You need to enable the JMicron PATA driver (Device Drivers->Serial ATA->JMicron PATA support)

Unnecessary:

  1. You should not need to enable IDE support to make this work. (Device Drivers->ATA/ATAPI/MFM/RLL)

Notes:

I have not yet tried burning to cd or dvd.
