Memory Errors:
If the POST detects a memory error
in the first 640KB of system memory, all of the first bank
memory is de-allocated and the test continues with the
second 640KB of the second bank memory. If the total
amount of error free memory becomes less than 2MB, a
2XX POST error occurs and the system stops. All of the
remaining memory is used as system memory. When the
POST memory test has completed, the usable memory
size is compared with the configuration data and if a
mismatch is detected, a 2XX error code occurs. The user
can continue with system operation by pressing F1 and
call for service at a later time.
The memory sizes that are de-allocated because of the
POST process is kept by the hibernation or suspend
functions. To test this memory, it must be re-configured as
part of the original memory size. The memory
re-configuring is done by turning power off and on.
De-allocation support is done only by the POST for
memory errors. All unrecoverable memory errors that
occur during normal operation cause an interrupt to the
operating system.
Error Log:
Diagnostic errors are printed on the printer
that is attached to parallel port when the error is detected.
The error is also logged in the system memory.
Use the following procedure to display the errors.
1. End the test, if it is running.
2. Press Ctrl
+
A to select the advanced diagnostic mode.
3. Press Ctrl
+
E.
4. The error log appears.
5. To exit the screen, select the cancel icon or press
Esc.
The error log is not saved when system power is turned
off.
