only with CD-Rs! this is the controller i'm using: port 0xd000-0xd007,0xd100-0xd103,0xd200-0xd207,0xd300-0xd303,0xd400-0xd40f mem 0xf8000000-0xf8001fff irq 19 at device 0.0 on pci3 the drive is pata: DVDR at ata4-slave UDMA33 also i'm getting the following warnings during the boot process: acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01 acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01 cheers.
