RAMPAGE CONFLICT WITH IBM PC I
|
||
|
||
|
||
An incompatibility exists between the AST Rampage! product and
|
||
the IBM PC-1 (with 64K motherboard). The problem has been
|
||
isolated to those machines with the early ROM BIOS, which is
|
||
dated 1981.
|
||
|
||
The user will get a "PARITY CHECK 2" error as the machine is
|
||
booting. The message appears on the screen as the REMM.SYS file
|
||
is executing.
|
||
|
||
One solution to this problem is the use of the "/X" option when
|
||
configuring REMM.SYS file. The exact command should read as
|
||
follows:
|
||
|
||
DEVICE=REMM.SYS /X=8800-A000
|
||
|
||
This will keep REMM from "looking at" RAM between the top of
|
||
conventional memory (544K on the early PC's) and the 640K
|
||
boundary, where REMM would normally start checking.
|
||
|
||
Another solution to this problem is to obtain from IBM the ROM
|
||
BIOS update kit. The "/X" part of the above command should not
|
||
be used.
