Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT
drive is configured as a Master. If it is a
1
(high), the drive is configured as a Slave.
In order to configure two drives in a Master/Slave relationship using the CS
jumper, you need to use a cable that provides the proper signal level at pin 28 of
the ATA bus connector. This allows two drives to operate in a Master/Slave
relationship according to the drive cable placement.
The Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT hard disk drives
are shipped from the factory as a Master (Device 0 - CS jumper installed). To
configure a drive as a Slave (Device 1- DS scheme), the CS jumper must be
removed. In this configuration, the spare jumper removed from the CS position
may be stored on the PK jumper pins.

You can also daisy-chain two drives on the ATA bus interface by using their Drive
Select (DS) jumpers. To use the DS feature, the CS jumper must not be installed.
To configure a drive as the Master (Device 0), a jumper must be installed on the
DS pins.
Note: The order in which drives are connected in a daisy chain has no
significance.

In combination with the current DS or CS jumper settings, the Slave Present (SP)
jumper can be implemented if necessary as follows:
Note: The CS position doubles as the Slave present on this drive.
• When the drive is configured as a Master
(
DS jumper installed
or
CS
jumper installed, and the Cable Select signal is set to (
0
), adding an
additional jumper (both jumpers DS and CS now installed) will
indicate to the drive that a Slave drive is present. This Master with
Slave Present jumper configuration should be installed on the Master
drive only if the Slave drive does
not
use the Drive Active/Slave
Present (DASP–) signal to indicate its presence.

The PK position is used as a holding place for the jumper for a slave drive in
systems that do not support Cable Select. The pins used for the parking position
are vendor unique.
