Owner`s manual

The RAM disk consists of RAM only, which is volatile.
Any attempt to reboot the system or loss of power to
the computer will result in a loss of data from the
RAM disk forever. You might forget this fact because
a
RAM disk resembles a real physical drive.
B. The portion of memory defined for RAM disk use is
unavailable
for any other use.
Before you can use the EDISK.syS program, you must iden-
tify the following memory types:
BASE memory is memory addresses OK-640K (00000-
9FFFFH). Every machine has some amount of base
memory; to
find out how much you have, run the DOS
CHKDSK.COM program to get an accurate total.
EXPANDED memory refers to a special memory accessed by
a bank-switching
technique that overcomes the OK-640K
(00000-9FFFFH)
limitation. If you have memory space
defined under the Lotus/Intel/Microsoft Expanded
Memory Specification (EMS), you can use EDISK.syS to
define a RAM disk in this memory space. EDISK.syS
will work with all EMS-compatible memory boards
used in the IBM PC, AT and compatible computers.
EXTENDED memory exists only on the IBM PC AT and
AT compatibles, where the memory addresses are 1 to
16 M (lOOOOO-FFFFFFH). Since few application soft-
ware
programs run in extended memory, using
