Appendix C
Hard Disk Drive Specifications and
Jumper Settings
This appendix provides specifications and jumper settings for the Conner 1.6-GB and
Seagate 2-GB hard disk drives used in the PowerMate P series computer configurations.
Table 1-1 and Table 1-2 in Section 1 identifies the which hard disk drives ship in which
configurations. NEC part numbers for the hard drives are provided in Sections 5.
The standard IDE hard drive is set as the master device on the primary IDE connector. The
drive is connected via a three-connector IDE cable to the system board.
The drive is auto-configurable, meaning that once the master/slave jumpers are set, the hard
disk type is automatically detected by the system and the remaining drive parameters are
automatically set by the system. (See Section 2, “Setup and Operation,” for information on
auto setup using the Autotype Fixed Disk parameter.)
