Check /var/log/messages or run /bin/dmesg right after booting. If you
have a recent standard kernel, it should detect the cdrom drive and load
a driver for it.
Mine looks like this:
Aug 31 11:03:16 whitewave kernel: scsi 5:0:0:0: CD-ROM PLEXTOR DVDR PX-712A
1.03 PQ: 0 ANSI: 5
Aug 31 11:03:17 whitewave kernel: sr0: scsi3-mmc drive: 125x/125x writer cd/rw xa/form2
cdda tray
Aug 31 11:03:17 whitewave kernel: Uniform CD-ROM driver Revision: 3.20
There may be other unrelated lines between these lines in the messages
file. Once you've verified that the kernel sees your drive and is
loading a driver, you can create inode entry in /dev with something like
this:
cd /dev
./MAKEDEV sr
Then you can create a symlink to /dev/cdrom
ln -s ./sr0 cdrom
Unless your system is screwed up in some other way, my sense is that
this should work. Otherwise you can use mknod to create the device.
Thanks, Nataraj and Mikkel. I think the problem is not Linux specific.
My machine has also got MS Windows, and MS Windows cannot also detect
my burner. I suspect that the problem is caused by the fact that I did
recently a BIOS update.
My motherboard is a Gigabyte GA-8I945PL-G and my burner is an IDE one.
Any ideas?
