Trouble mounting my CDROM

[mwade]

Hello,

sorry for the long post, just trying to give all the info that I can.
I am pulling my hair out trying to mount my CDROM on my Fedora Core 3. The CDROM was working, then I tried to access it and it was no longer showing any of the files listed on the CDROM. I know the CDrom works b/c I fired up Vmware on the same box and I can read the CDROM under windows. The disk mgt in the GUI said that the CDROM is set to auto. When I cd to the /media directory the CDROM dir is there, but nothing it, and there should be. Here is what I have tired.

mount /dev/hdc /media/cdrom - mount /cdrom - mount /media/cdrom
mount -t /dev/hdc /media/cdrom - mount /mnt/cdrom - and on and on.

I have tried everything in man mount.
My fstab config is the following:
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/hdd /media/cdrecorder auto pamconsole,fscontext=system_u:object_r:removable_t ,ro,exec,noauto,managed 0 0
/dev/hdc /media/cdrom auto pamconsole,fscontext=system_u:object_r:removable_t ,ro,exec,noauto,managed 0 0

When I try and access the CDROM via the GUI i get the following error:
-unable to mount the selected volume. the volume is probably in a format that cannont be mounted.
Show more details: mount: wrong fs type, bad option, bad superblock on /dev/hdc, or too many mounted files systems

I then look to see if I have to many Files systems mounted. See below:
[root@Linux media]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) none on /proc type proc (rw) none on /sys type sysfs (rw) none on /dev/pts type devpts (rw,gid=5,mode=620) usbfs on /proc/bus/usb type usbfs (rw)
/dev/hda1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

I then rebooted to see if that works. Still nothing (and during these tests VMWARE was NOT active so there is no conflict). The dmseg says the following:

Thanks in advance.

Try turning off APIC (Advanced Programmable Interrupt Controller) in the BIOS. It is only useful for multiple CPU setups, and it is known to cause problems with some motherboards with only a single CPU. If you can't turn it off in the BIOS, pass 'noapic' as a kernel boot parameter. Another possibility: make sure that Plug n Play OS is set to No/Disabled in the BIOS.
