ADT, I'm seeing this screen shot of your system?
It appears you have an optical drive from Lite-On?
ADT, you may have issues concerning your optical drive. IE: If the PC info you posted is correct then you have a 4 -6 year old system, the drive spec for your particular system is a Lite-On 16X DVD
Model LTD-1665, lite on merged this particular drive w/JVC so the new model name is:
JLMS-X LTD 1665 to which no firmware or
drivers exist.
OS 7 uses a standardized
driver catalog since OS 7 does not see the drive what so ever I recommend you reboot to see if your BIOS recognises the drive and then we can trouble shoot further.
