The AST SixPak 286 board offers flexible and powerful memory enhancement for
the AST Bravo/286, AST Premium/286, AST Premium Workstation, IBM PC/AT and
compatible computers.  It offers complete software compatibility with Expanded
Memory Specification (EMS) 4.0 software.

The SixPak 286 SmartSwitch configuration software eliminates the need to set
board switches. The software can make the optimal settings for your computer
automatically, or you can select your configuration from easy to use menus.
The SixPak 286 board retains your selected configuration even when your
computer is turned off.

You can upgrade your SixPak 286 board's memory to a maximum of four megabytes
(MB) with single inline memory modules (SIMMs) that snap in and out of your
board socket's.  Optional I/O Pak 286 (AST P/N 500560-002) piggyback boards
add one serial port and one parallel port to your SixPak 286 board.


JUMPER SETTINGS

To set the board Identification jumper (E9 through E12): If this is the first
SixPak 286 board in your computer, place the jumper on E9. For the second
board use E10, the third board, E11 and the fourth board, E12. In addition, to
use automatic mode after adding or removing memory, you must set the default
configuration jumper (E8) to the alternate position. This clears the old
configuration. For example, if the jumper is on pins 2 and 3, move it to pins
1 and 2.  Also,the jumper on (E7) should remain installed to enable parity
error reporting. Jumpers (E1 thru E5) tell the SixPak 286 the amount of memory
on the board, for 512K and 1MB the jumpers should be in the 1-2 position, for
2MB and 4MB the jumpers should be in the 2-3 position.
