The cdrom won't mount.

i/p: mount /dev/cdrom /mnt/cdrom
o/p: mount: you must specify the filesystem type

i/p: mount /dev/cdrom /mnt/cdrom -t iso9660
o/p: mount: /dev/cdrom has wrong major or minor number

Mounting worked using Red Hat 5.2 and 6.0. It worked on installs of Red Hat
6.1. The machine it's not working on was a machine that was upgraded from

The same is true for the floppy.

Looks like your /dev tree got messed up.
Make sure /dev/cdrom is a link to the actual drive (usually /dev/hdc (IDE) or
/dev/sr0 (SCSI)).

Actually, this looks like a buglet I've had a few times on my system, where the
reported error message is always the one displayed. If so, then you have the
filetype in /etc/fstab set to "auto" and iso9660 compiled as a module and NOT
loaded when you issue the command.

I've had the same problem with /dev/fd0 set to "auto" and vfat compiled modular
- I don't have msdos compiled in at all. For some reason, even if one specifies
the filesystem type, the kernel makes no attempt to load the module in this
