Mounting CDROM issue

[dylanz]

I'm having a hard time mounting my cdrom drive. Here are some details:

> dmesg

cd0 at scsibus0 targ 0 lun 0: <HL-DT-ST, DVDRW GS23N, SB07> ATAPI 5/cdrom removable
cd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 6

16 partitions:
#            size     offset     fstype
   c:   2518848         0       unused
#

> mkdir /cdrom
> mount_cd9660 /dev/cd0a /cdrom
mount_cd9660: /dev/cd0a on /cdrom:  Device not configured

I've tried a bunch of combinations in /etc/fstab as well, but no luck thus far. This is on a base install of 4.7. I'd post the full dmesg, but I'm internet-less where the machine is.

Any suggestions welcome!
