Master configuration is used for all single drive applications,
and master or slave configuration (only one of each per port) is
used for two drive applications. Use the information in the following
tables for information on how to set Master/Slave jumpers.

The following jumper information applies to Toshiba's current line
of Hard Disk Drives.
Master
configuration is obtained by setting jumpers B, C & D open (no

When B-D jumper is installed, the drive is configured as cable select.
If pin 28 = Low, the drive is master. If pin 28 = High, the drive
is slave.
