No longer able to mount cdrom

[~Jase]

Greetings,

A big thanks for all the replies on my last subject of "True DOS prompt
for NT?".

I'm facing another dilemma now with another Linux (RH5) box.  I removed
the internal cdrom drive that it had and replaced it with another older
slower one.  The problem now is that it no longer mounts the cdrom
drive.  I get error messages that it can't find /mnt/cdrom,
/dev/cdrom...etc.  I haven't changed anything, only the actual device.
Am I missing something?  Thank you.
