AST-3G PLUS/MEMORY ERROR MESSAGE
|
||
|
||
|
||
A problem has been discovered when using AST-3G Plus
|
||
emulation when the board is installed in IBM Model 339 AT or
|
||
compatible PC's. This problem could occur in either "CGA"
|
||
or "HERCULES/PREVIEW" emulation modes.
|
||
|
||
|
||
The problem occurs when the PC is warm booted. On a cold
|
||
boot the problem does not occur. Depending on the type of
|
||
machine, either the message "CONFIGURATION TOO LARGE FOR
|
||
MEMORY" or "PARITY CHECK TWO" will appear after a warm boot.
|
||
The PC will "lock" and will have to be powered down.
|
||
|
||
|
||
To prevent this from occuring, AST-3G diagnostics diskette
|
||
version 2.26 is required. After cold booting the machine,
|
||
run the program "EMUL ON", which is contained on the
|
||
diagnostics diskette. This will load a keyboard intercept
|
||
routine, which will prevent the memory error from occuring
|
||
after a warm boot. This program must be run every time the
|
||
machine is powered on to prevent the recurrence of the
|
||
problem.
