CD-ROM drive (not available on all models)
(1)
The CD-ROM drive is connected to the secondary IDE port and configured as a master drive.
NOTE:
When installing a CD-ROM drive, make sure that the
hard disk drives are on one channel and the CD-ROM drive is on
another. If you install a CD-ROM drive on the secondary/master
channel and a hard disk drive on the secondary/slave channel,
you might get a POST error and BIOS autodetect error. In
addition, the hard disk drive on the secondary channel will be
slowed to the same speed as the CD-ROM drive, resulting in poor
hard disk drive performance and speed.
