itsme86 is right. In the 2.6 kernel scsi emulation is not necessary. Heres how you can track down your cdrom drive:
Code:
# dmesg | grep hd
Kernel command line: root=/dev/hdb2
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
hda: WDC WD800JB-00ETA0, ATA DISK drive
hdb: MAXTOR 6L060J3, ATA DISK drive
hdc: GENERIC DVD DUAL 4XMax, ATAPI CD/DVD-ROM drive
hda: max request size: 1024KiB
hda: 156301488 sectors (80026 MB) w/8192KiB Cache, CHS=16383/255/63, UDMA(100)
hdb: max request size: 128KiB
hdb: 117266688 sectors (60040 MB) w/1819KiB Cache, CHS=65535/16/63, UDMA(133)
hdc: ATAPI 40X DVD-ROM DVD-R CD-R/RW drive, 8192kB Cache, UDMA(33)
Adding 1044216k swap on /dev/hda3. Priority:-1 extents:1
EXT3 FS on hdb2, internal journal
In my case the cdrom drive is /dev/hdc so cdrecord is:
Code:
# cdrecord dev=/dev/hdc -scanbus
That should show you your cdrom drive.
