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 across
J4.1 and J4.3 this jumper has no effect but provides
you with a spare.
