[comp.sys.ibm.pc] RAM Disk in Extended Memory

harvey@nems.dt.navy.mil (Harvey) (10/07/89)

Does anyone know how to use extended memory from 640K - 1 Mb
as a RAM Disk.  VDISK only has an option for using extended
memory above 1MB.  Is there another RAM disk driver that will
do the job?

I used to run vdisk.sys in extended memory on a PC's Limited 286/12 which
only had one mb of ram, and it was definitely in extended memory (Using
PC-DOS 3.1).

You shouldn't really have any memory between 640k and 1Mb. This memory
is for the screen, and the ROM Bios.
If you have a computer with 1 Mb memory, you either have 384kb
extended memory, or a very incompatible computer.

  So, many of us have *very incompatible* compatible computers, since
we have 1MB memory and no extended but 384K shadow RAM.  I am confused,
please HELP!
