The AST RampagePlus 286 board offers flexible and powerful memory enhancement
for the AST Bravo/286, AST Premium/286, AST Premium Workstation, IBM PC/AT,
IBM PS/2 Model 30 286,and compatible computers.  It offers complete hardware
compatibility with Expanded Memory Specification (EMS) 4.0 software.

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

You can upgrade your RampagePlus 286 board's memory to a maximum of eight
megabytes (MB) with single inline memory modules (SIMMS) that snap in and out
of the board sockets.  The optional I/O Pak 286-SP Piggyback board (AST P/N
500560-002) adds one serial port and one parallel port to your RampagePlus 286
board.  The RampagePlus 286 board has four pairs of sockets called banks.
Rampage Plus 286 can use 256K or 1MB SIMMs in combinations up to 8MB.  DO NOT
MIX SIMM SIZES AND SPEEDS WITHIN A BANK THIS WILL CAUSE ERRORS.


CHANGING THE DEFAULT JUMPER

To use automatic mode after adding or removing memory, you must set the
default configuration jumper (J3) to the alternate position. This disables the
memory on the board until you reconfigure it with the SmartSwitch (RAMP.COM)
program.  For example, if the jumper is on pins 1 and 2, move it to pins 2 and
3, if the jumper is on pins 2 and 3, move it to pins 1 and 2.
