MEMORY DOCUMENTATION
====================

VERSION 1.01 8 NOV 1982 (C) MICROLIFE, INC. (301) 799-5509


Memory is a utility to allow dynamic setting/resetting of the amount

of memory used by DOS. The major advantage is that the system switches

can be set to anything your heart desires, with the knowledge that you

should not have to open up the PC to set switches while using MEMORY.

For example, some games (like ZORK and Adventure) seem to require a

maximum of 320K, the switches can be set for the 128K and then MEMORY

can be run to set DOS for larger amounts or smaller amounts of memory

as required. MEMORY can be used in batch files or simply run from the

system prompt to set DOS memory size from 64K (lowest switch setting)

up to 640K. More specific parameter information is as follows:

MEMORYRestores DOS memory size to what it was prior to
running MEMORY. Follow the example below:

Step 1 MEMORY 3Sets DOS to 192K
Step 2 MEMORY 5Sets DOS to 320K
Step 3 MEMORYRestores DOS to 192K

MEMORY 0Forces DOS read the value of the switches on the
motherboard.

MEMORY N(Where N can be a decimal number from 1 to 10). Installs
N times64K of memory to DOS. That is, assuming N was 7,
7 * 64K = 448K. A very important note here is that the
DOS can now be set to beyond the value of the switches
(544K Maximum) to 640K !!


An example of MEMORY used in an Autoexec file:

CommandsDescription of each command
.............................................................................

PWRUPCLKSets the System time equal to the Quadboard time
MEMORY 9Sets DOS memory size to 9 * 64K = 576K !!!
RAMDISK 10/ACreates a Ramdisk of size 10 * 32K = 320K
COPY *.* D:Copies all of Drive A: to Drive B:
D:Logs onto Drive D:
CHKDSKChecks the Disk Parameters

............................................................................






Special Notes:

1. MEMORY resets the system when run, except in the cases of bad para-
meters entered or when the same command is run more than once.
2. MEMORY will only install up to the available RAM present in the system.
For example, you have 320K in the system, a command like MEMORY 6 would
result in an error and no change from the present memory size.
3. The QD Ramdisk software provided with the Quadboard reads the memory
size from the switches on the motherboard, not what DOS thinks it has.
By doing so, the maximum size of memory under the Ramdisk (reading
the switches) is 544K bytes.
