Errors during the POST (SelectaDock II - III)
Errors during the POST
If the POST detects an error, a three- to eight-digit
error code displays.
Memory Errors
If the POST detects a memory error in the first 640 KB of
system memory, all the first bank memory is deallocated and
the test continues with the second 640 KB of memory.
If the total amount of error-free memory becomes less than
2 MB, a 2XX POST error occurs and the system stops.
All 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. If a mismatch is detected, a 2XX error
code occurs.
The user can continue with system operation by pressing Esc, and F1 after restart
and call for service at a later time.
The memory that is deallocated because of the POST process is
kept by the hibernation
or suspend functions. For this memory to be tested, it must
be reconfigured as part of
the original memory size. You Configure
by turning the power off and on.
Deallocation support is done only by the POST for memory errors.
All irrecoverable memory errors that occur during normal operation cause
an interrupt to the operating system.
