8051A DUAL DRIVE SUPPORT


The 8051A operates in a MASTER SLAVE relationship. This enables the 8051A to
be daisy-chained with another IDE drive (i.e. 7080A, 7040A, or another 8051A).

1: Jumpering J4.1 to J4.2 causes the 8051A to operate in the SLAVE role.

2: Jumpering J4.5 to J4.6 causes the 8051A to operate in the MASTER role.

3: Jumpering J4.3 to J4.4 This allows the 8051A to be compatable with
some BIOS versions that cannot support 1:1 interleave. This jumper
should not be installed under normal conditions.

4: Jumper J4.7 to J4.8 is not used and should not be installed.

5: Jumpering J4.9 to J4.10 enables the I/O ready signal onto the
interface connector, pin 27.

To operate the 8051A as the ONLY DRIVE in a system, J4.1 thru J4.10
should all be open (not jumpered) except as noted below.

NOTE: The 8051A may be shipped with a jumper accross J4.1 and J4.3
this jumper has no effect but provides you with a spare.
