Alternate capacity jumper

This jumper lowers the drive capacity by setting the default translation to

4,092 cylinders and causes the drive to appear to your BIOS as having

a capacity of 2.1 Gbytes. Some BIOS that only auto-detect may require

this jumper. Place a jumper on pins 1 and 2 of the J5 options jumper

block to enable this option. When installing this jumper, you may need

third-party partitioning software to achieve full capacity of the drive.

Computers that use cable-select determine the master and slave drives

by selecting or deselecting pin 28, CSEL, on the interface bus. Master

and slave drives are determined by their physical position on the cable.

• The drive plugged into the I/O connector that carries the CSEL signal

is the master.

• The drive plugged into the I/O connector that does not carry the CSEL

signal is the slave.

To configure the drives for computers that use cable select:

• Install jumpers on pins 5 and 6 and pins 7 and 8 as shown in

Figure 4 on page 20.

• Connect the drives to the cable as shown in Figure 5 on page 22.

The diagnostics jumper activates a drive feature called EZConfig.

EZConfig allows the advanced user to enable, disable or change the size

of the read and write cache and to configure PIO mode 4 capability. To

use EZConfig, follow the procedure below.

1. Place a jumper on pins 6 and 8 of the options jumper block.

2. If you have more than one hard drive, remove the drive you do not

want to test. Connect the test drive to the primary channel on the host

adapter.
