Do not use RamDisk.Sys.  The correct driver to use to set up extended
memory as a RAM drive is VDISK.SYS.  The syntax you need to use is:

DEVICE=VDISK.SYS[bbbb][sss][eee][/E:{max}]
where
  bbbb = specifies the virtual disk in size Kb.  The minimum value you
         can specify is 16; the maximum is determined by the amount of
         free memory on your computer.  The default value is 64 Kb.
 
  sss = specifies the sector size in bytes.  The value may be 128,
        256, or 512.  The default value is 128 bytes.

  eee = specifies the maximum number of entries alloed in the root
        directory of the virtual disk.  The minimum value is 16; the
        maximum is 1024.  The default value is 64.

So, you would put in you config.sys:

DEVICE=C:\DOS\VDISK.SYS 1024 /E

If your extended memory requires a driver for some programs to
recognize it, place it before the above statement in your config.sys
file.  (i.e. DEVICE=C:\DOS\AEMM.SYS)

Hope that helps...
