   COMPAQ DESKPRO M FAMILY

      The following information pertains to the Compaq Deskpro 386/25M,
      386/33M, 486s/16M, 486s25M, and the 486/33M.

      These Compaq Deskpro systems come standard with 4MB on the system
      board. These system boards are expandable to 64MB using Intel 72-pin
      memory modules in a Compaq 60MB memory expansion board.

      NOTE: Adding memory beyond the processor board's 4MB of memory
               requires purchasing the optional Compaq memory expansion
               card (Compaq part number 129160-001).
