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.

            NOTE: The above settings define how much of the memory on the
                  Advantage will be used as conventional (base 640K) and/or
                  extended linear memory.  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.

        DUAL PAGE MODE

            NOTE: Dual page mode allows expanded memory to maintain two sets
                  of mapping registers, which ensures proper multitasking
                  operation.  Generally, dual page mode is enabled. (SW1-9 ON)

            MEMORY PAGED (EMS)

            SW2-8 - Memory Parity Checking

            The above list of addresses is not complete.  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.

    NOTE: In normal RS232 operations, the Data Carrier Detect (DCD), Data Set
          Ready (DSR), and Clear To Send (CTS) are driven by the external
          serial device.  In rare cases, one or more of these signals must be
          "forced true". To force a signal true, remove the appropriate jumper
          above.
