Hard Drive

All systems ship with one internal 3 1/2-inch hard drive (1-inch high, thin-
height) installed in the internal drive slot, at the front of the system. Drives are
available in a 2.1-GB, 4.3-GB, 6.4-GB, and 8.4-GB IDE Ultra DMA models.
The riser board has two IDE/PCI interface connectors (primary and secondary)
for connecting IDE storage devices. A two-connector hard drive IDE cable
connects to the IDE hard drive and the primary connector on the riser board.
Each connector (primary and secondary) supports up to two IDE devices.
Note: Physically, the chassis contains room for three
storage devices. Logically, the riser board supports four
storage devices.
Hard drive jumper settings are given in Section 2, "System Configuration."
Connector locations for the IDE hard drive connectors on the riser board are
given in Section 5, "Riser Board." Section 6, "Illustrated Parts Breakdown" lists
the NEC CSD part numbers for the hard drives. Hard drive specifications are
