I had to create it manually with mknod. When you make CD devices with MAKEDEV, it makes the number of devices you specify on the command line. Specifying 'cd1' makes 1 device, cd0. You want to type 'sh MAKEDEV cd2' to make cd0 and cd1 devices. > Maybe the mixture of ATAPI and SCSI cdrom confuses the system. > The systems unit numbering is not reflected correctly in the messages. I suspect your device nodes may be messed up. Can you send the output of: camcontrol devlist -v ls -l /dev/*cd* Make sure you CC your reply to FreeBSD-gnats-submit@FreeBSD.ORG so it goes into the audit log for this PR.

That is why you were able to mount cd0 as cd1. As for why you couldn't mount cd0 -- were you root when you tried to mount it? Try re-making your CD devices, like this: sh MAKEDEV cd4 That will make cd0->cd3. Ken -- Kenneth Merry ken@kdm.org "Kenneth D. Merry" wrote: > cd1{a,c} and cd0{a,c} both have the same minor numbers.

But even with this setup I could not mount cd0c but only cd1c. > > As for why you couldn't mount cd0 -- were you root when you tried to mount > it? Yes. If not I get the message: 'cd9660: Operation not permitted.' But what I got was 'Device not configured' > > Try re-making your CD devices, like this: > > sh MAKEDEV cd4 > > That will make cd0->cd3. This cleanup solved the problem. But it is exactly what I have done before but only with MAKEDEV cd1. There are only 2 SCSI CDROMS (0 and 1). What I have changed in the meantime were the SCSI IDs because in messages the cd1 was probed before cd0. But now if I change it back it also works. So no idea what was the reason. Many thanks !.
