EIDE Device Installation Guidelines
Jumper Settings
All EIDE drives should be configured for the Cable Select jumper position,
which assigns master and slave status to drives by their position on the
interface cable. When two EIDE drives are connected to a single EIDE
interface cable and are configured for the Cable Select jumper position, the
drive attached to the last connector on the interface cable is the master, or
boot device (drive 0), and the device attached to the middle connector on
the interface cable is the slave device (drive 1). Refer to the documentation
in your drive upgrade kit for information on setting devices to the Cable
Select jumper position.
General Guidelines
With the two EIDE interface connectors on the system board, your
computer can support up to four EIDE drives:
•The primary EIDE system-board connector should be cabled to EIDE
hard drives
•The secondary EIDE connector should be cabled to EIDE CD, DVD,
tape, DAT, and zip drives
To locate the EIDE interface connectors on the system board, see "System
Board Components" or the interior service label. Each EIDE interface
connector on the system board supports the following:
•Two channels, master and slave
•LBA
•PIO Mode 3 and Mode 4
•UDMA Mode 3, Mode 4, and Mode 5
•Ultra ATA/100 (backward-compatible with ATA/66 and ATA/33)
