Scsi??

[Elijah]

I'm sorry I'm quite new to (still) my hardware. How do I know what kind of scsi controller I have in linux?? or if a scsi exists in my system ?? :D
I want to re-compile my debian kernel, I have a liteon ltr-16102. I'm not really sure if even use scsi, sorry I'm still a newbie even from my own hardware :(

most kernels come with SCSI support
# ls -l /dev | grep cdrom
to see what your cdrom points to, it should be sr0 , sr1 e.t.c
# cdrecord - scanbus
see if your CD/RW is listed
--
if not listed, to fix it just add to your lilo.conf or grub.conf just one line
"hdc=ide-scsi" (hda - primary master, hdb - primary slave, hdc - secondary master, hdd - secondary slave)
---
the idea is that an IDE device must emulate a SCSI device.

tell us if it works.

Very informative links, Thanks

btw, now that I know that I have scsi, is there a way to identify it's scsi host adapter? I could use that info once I compile ...

The Liteon you have is a IDE cdrw.

It uses scsi emulation and not a actual scsi controller.

[rid3r]

if you are still here, Elijah:
# cat /etc/fstab
look for
/dev/csd0 /mnt/[the_mount_point ...... ro (you change it to rw (read-write))

oh, I see. I have no scsi then.

hmmm I got /dev/cdrom1 for my cdrw, ok I changed it now to rw.

Many thanks guys :p

/dev/csd0 should actually be /etc/scd0
