MP-MINI MEMORY ADDRESSING
|
||
|
||
|
||
It has been determined that there is potential for the MP-Mini to
|
||
cause memory errors under certain conditions.
|
||
|
||
These problems could occur when using the 256K MP-Mini
|
||
configuration (without the Mini-Pak).
|
||
|
||
The MP-Mini has no hardware method of determining where memory
|
||
addressing should stop if the MP-Mini is not fully configured
|
||
with 384K of RAM. The board is meant to start at an address of
|
||
256K and end at 640K. If any software application attempts to
|
||
establish the amount of memory available with only 256K of Ram
|
||
on the MP-Mini installed, a "parity check two" error could be
|
||
generated, locking the machine up.
|
||
|
||
One program where this occurs is with Norton Utilities' "SYSINFO"
|
||
program. This program checks to see what equipment is installed
|
||
in the PC. When it attempts to check memory size with a 256K MP-
|
||
Mini installed a "parity check two" error is generated.
