Power-on self-test (POST)
POST
Phoenix POST, which checks the standard PC AT components of the
mother board to verify that they are functioning correctly, is used as
standard. Phoenix POST has been expanded to include a number of
functional tests in order to be able to test POS-specific functions.
The error messages are output on the cashier display, the external cashier
display or the monitor. The cashier display and monitor have high priority,
and the messages are always output on the monitor if the VGA card is
plugged in. Error messages are only output on the external cashier display
if there is no monitor or cashier display connected.
The error messages are output on the cashier display in the following
format:
TEST POS TEST TYPE ERRORNUMBER
Error text
The error messages output during the test are always in English. The
following is an example of an error message output on the cashier display:
TEST POS MC 02
BATTERY EMPTY
ANY KEY TO RETRY
During the POST, static errors are localized with a high degree of
reliability; sporadic errors are localized only to a limited extent.
Please contact your customer service engineer or the customer service
department if POST reports an error. The MS-DOS critical errors and
POST error messages are listed below.
You will find more information on MS-DOS system error
messages on page GB - 62.
