CD/DVD-ROM Drive Jumper Settings

The CD/DVD-ROM drives are connected to the system board secondary

drive connector at the factory. CD/DVD-ROM drive jumpers are set as the master drive, as shown in Figure 5-11. If an additional hard disk drive is connected to the secondary connector, it must be set as the master drive (see1 in figure 5-7) and the CD/DVD-ROM drive jumpers reset as the

slave drive as shown in Figure 5-11.

Note: For models that have a factory-installed Zip drive, the Zip drive is jumpered as slave and the CD/DVD-ROM drive is jumpered as master. See “Zip Drive” on page 5-14

Check the Setup Utility for correct installation.
