Sorry for the length of this, but I am including stuff from various logs. I have a CDRW and a DVD drive on my machine. Boot messages show that both are identified correctly. Initially, I couldn't play music CDs, but I followed a couple of articles from the SuSE knowledge base & got that to work (enabled scsi emulation, etc.). But whenever I use Yast2 to install software from the CD's, it always wants me to put the CD in the DVD drive. It works fine so I guess it's not really a big deal, but I want to understand what's going on. Below are some excerpts from various logs: <4>Kernel command line: auto BOOT_IMAGE=linux ro root=342 hdc=ide-scsi <4>ide_setup: hdc=ide-scsi ......<snip> <6>Uniform Multi-Platform E-IDE driver Revision: 6.31 <4>ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx <4>SIS5513: IDE controller on PCI bus 00 dev 15 <4>SIS5513: chipset revision 208 <4>SIS5513: not 100%% native mode: will probe irqs later <4>SiS735 <4> ide0: BM-DMA at 0xff00-0xff07, BIOS settings: hda:DMA, hdb:DMA <4> ide1: BM-DMA at 0xff08-0xff0f, BIOS settings: hdc:DMA, hdd:DMA <4>hda: MAXTOR 6L080J4, ATA DISK drive <4>hdb: IC35L060AVVA07-0, ATA DISK drive <4>hdc: LITE-ON LTR-32123S, ATAPI CD/DVD-ROM drive <4>hdd: LG DVD-ROM DRD-8160B, ATAPI CD/DVD-ROM drive <4>ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 <4>ide1 at 0x170-0x177,0x376 on irq 15 <4>hda: safely enabled flush <6>hda: 156355584 sectors (80054 MB) w/1819KiB Cache, CHS=9732/255/63, UDMA(100) <4>hdb: safely enabled flush <6>hdb: 120103200 sectors (61493 MB) w/1863KiB Cache, CHS=7476/255/63, UDMA(100) <4>hdd: no flushcache support <4>hdd: ATAPI 48X DVD-ROM drive, 512kB Cache <6>Uniform CD-ROM driver Revision: 3.12 ......<snip> <6>scsi0 : SCSI host adapter emulation for IDE ATAPI devices <4> Vendor: LITE-ON Model: LTR-32123S Rev: XS0X <4> Type: CD-ROM ANSI SCSI revision: 02 <4>Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 <4>sr0: scsi3-mmc drive: 209x/40x writer cd/rw xa/form2 cdda tray
