Advantage Premium AST Part Number 202106-001 The Advantage Premium is a multi-function memory expansion adapter for the IBM PC/AT and 100% compatibles running at 8MHz. Memory can be expanded on this board from 512K to 1024K, and up to 2048K with an optional daughter board, using industry standard 256K dynamic RAM chips with a minimum speed requirement of 120NS. Memory standards supported by the Advantage Premium include conventional (base 640K), linear extended, LIM 3.2, LIM 4.0, and EEMS. The Advantage Premium comes standard with a serial port configurable as COM1: or COM2: and a parallel port configurable as LPT1: or LPT2:. A second serial port and a game port can be optionally be added.

Any memory not used by these settings will be available as EMS expanded memory. If the Advantage is to be used exclusively as EMS expanded memory, set the switches on Bank 2 (below) accordingly, and the above settings will be ignored.

After the 3072K address, we have listed the settings for every megabyte only. Switches 5,6 & 7 determine the addresses between. If you are unable to interpolate the correct starting address from the above information, contact AST to order the complete documentation. NOTE: Linear memory installed previous to the Rampge would consist of Base memory (maximum 640K) plus extended memory (non-EMS) installed in the system before the Advantage is installed. If the starting address is set below 640K, the Advantage will automatically "backfill" base memory up to 640K, with the remainder of linear memory going to extended memory. You will have to adjust your machines CMOS with your set-up program only if you add conventional or extended linear memory with the Advantage. Do not change the set-up to reflect expanded EMS memory.

In rare cases, one or more of these signals must be "forced true". To force a signal true, remove the appropriate jumper above.
