Finding my CDROM


Hi,

After a very steep learning curve, I seem to have managed to compile a custom kernel (2.4.22) for my box. It's a rather ancient beast that I use for playing with. I have the SMP support, RAID (DAC960) support and CD-ROM (TEAC hanging off an Adaptec card) working (I think!!!) but I have no idea what device the CD-ROM is so that I can mount it!

Can anyone help?

The output of dmesg is:-

Thanks, but I don't think it can be

In my fstab, there is the line:

/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0

/dev/cdrom is a link to /dev/scd0

if I try to mount /mnt/cdrom, I get the error message:

mount: /dev/cdrom is not a valid block device

So I am assuming that /dev/scd0 is the wrong device (or there is another problem....?)

Any other ideas?

Paul

you could have left some crap out in your kernel config about scsi cdroms, but let somebody else give it a shot. i've got to go.

possibly scsi1

but yeah, check that you compiled in the necessary scsi drivers in your kernel. looks to me like thats ok, though

Stoopid me!

Thanks to everyone whop has had a look at this for me. Problem now solved!

It turned out that even though I had compiled support for the Adaptec and for the ISO filesystem, I hadn't included support for CD-ROMs.... OOps!

Thanks again,
