Command: fdxms286.sys

  FDXMS286.SYS is an extended memory driver for FreeDOS.
  FDXMS286.SYS is for 286 computers. FDXMS is for 386+ computers.
  FDXMS286.SYS has to be loaded in CONFIG.SYS / FDCONFIG.SYS.
  FDXMS286.SYS is out of date. You should use HIMEMX or JEMMEX
  instead.

Syntax:

  DEVICE=[drive][path]\fdxms286.sys [options]
         drive  The drive letter, e.g. C:

Options:

 NUMHANDLES=  Sets the number of XMS handles. Default is 32. Minimum
              is two (not much use of XMS without any handles!) and
              maximum is currently 1024. Each handle takes 5 bytes
              (FDXMS.SYS) or 9 bytes (FDXXMS.SYS).
  BIOS        Makes FDXMS286 always call the BIOS through INT15
              instead of using its own protected mode switching.
  PS          Changes to the particular A20 handling necessary on
              PS/2 machines.
  GEODE       Removes delays while changing the A20 line. Reported
              to help FDXMS286 to work on National Semiconductor's
              Geode GX1 processor.
  DELAY=      Number of calls to the delay routine after changing
              the A20 line. If you receive the error message "Unable
              to switch A20 address line", try setting it to a big
              value (say 4000) and see if it helps. Then fine tune
              it as you want as low a value as possible for speed.
              Default is 1. Maximum is 65535 and 0 maps to 65536.
