Courtney,
I don't have a 2.0 kernel with scsi, but I do have a 2.2 one with a
scsi cdrom. Sorry, I didn't see if someone had already answered your
question.
1) you should see some boot messages that your CDROM is recognized.
Look through the output of 'dmesg'. Here's what ours looks like at
home. We have 2 devices on the SCSI bus:
sym53c8xx: at PCI bus 0, device 11, function 0
sym53c8xx: 53c810a detected
sym53c810a-0: rev=0x12, base=0xe7000000, io_port=0xe400, irq=10
sym53c810a-0: ID 7, Fast-10, Parity Checking
sym53c810a-0: restart (scsi reset).
scsi0 : sym53c8xx - version 1.3g
scsi : 1 host.
Vendor: YAMAHA Model: CRW4416S Rev: 1.0g
Type: CD-ROM ANSI SCSI revision: 02
Vendor: SCANNER Model: Rev: 2.02
Type: Scanner ANSI SCSI revision: 01 CCS
Detected scsi generic sgb at scsi0, channel 0, id 6, lun 0
Or, look in /proc, (but this might not be in 2.0.30
$ cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 03 Lun: 00
Vendor: YAMAHA Model: CRW4416S Rev: 1.0g
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: SCANNER Model: Rev: 2.02
Type: Scanner ANSI SCSI revision: 01 CCS
2) Your /dev/scd0 device should display as follows when you
[eric at curious /dev]$ ls -l /dev/scd0
brw-rw---- 1 root disk 11, 0 May 5 1998 /dev/scd0
If it doesn't, then cd /dev
./MAKEDEV sr
should create them for you.
I think that sr0 used the be the 'old' name of the scsi cdrom. maybe
it is named 'sr0' instead on 2.0.30?
3) Maybe it really isn't built into the kernel or some other piece is
missing, like the hostadapter - or possibly it was built as a module
and you need to do an 'insmod' on the appropriate kernel drivers.
Regards,
-Eric.
