2.4.2.1 Medalist drive as master
The Medalist drives provide for three ways the slave can identify itself.
You can configure the Medalist drive for a slave that is:
An ATA-compatible drive
A non-ATA-compatible drive that does not conform to the DASP–
timing parameter of the ATA spec
A non-ATA-compatible drive that does not conform to the DASP–
timing parameter of the ATA spec but negates PDIAG– when the drive
is ready
2.4.2.2 Medalist drive as slave
The Medalist drive conforms to the ATA standard for slave identification.
If the master drive is a non-ATA-compatible drive, it may not recognize
the Medalist drive in the slave position. We recommend that you config-
ure your Medalist drive as the master when used with a non-ATA-com-
patible drive.

2.4.3 Cable-select configuration

If your computer and both of your drives support cable select (CSEL),
you can use the cable select option to determine the master and slave.
To configure your drives to use cable select, you need to install jumpers
and to use a special cable-select cable as follows:
Install a jumper on pins 3 and 4 of the master/slave jumper block as
shown in Figure 3 on page 13. When a jumper is installed in this
position, the drive ignores the jumper installed on pins 7 and 8.
You must use an interface cable built for cable-select. To make a drive
the master, attach it to the connector that has the CSEL signal line
connected to pin 28. To make a drive the slave, attach it to the
connector that has pin 28 unconnected (CSEL is not carried to pin 28
of that cable connector.) Note that CSEL is grounded at the host.
