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

I would appreciate some help resolving this mount command on a freshly
installed RH 7.2 system.

 

The CD drive is a read only IDE device that was just used to reload RH 7.2
on an older Pentium 166 system. This is a Socket 7 FIC motherboard. RH 7.2
has not mounted this device before unless it mounts the CD when it installs
the operating system.

 

This was a server installation with a KDE desktop.

 

BIOS writes while booting: Found CD-ROM :  CDU511

 

Changing the media has no affect. The fstab entry looks valid to me:

 

/dev/cdrom        /mnt/cdrom        iso9660 noauto,user,kudzu,ro     0
0

 

The CD drive works fine from the uSoft half of the dual boot.
