Power On Self Test (POST)
POST
As standard the Phoenix POST is used, which monitors the functioning of
the standard PC AT components of the master board. The Phoenix POST
has been expanded by some function tests so that POS-specific functions
can also be tested.
The error messages are displayed on the external user display or the VGA
monitor. The user display and the monitor have high priority; with the VGA
card inserted the messages are always displayed on the monitor. Error
messages are displayed on the external user display only if there is no
monitor.
Display of the error messages on the user display has the following format:
TEST POS TEST TYPE ERROR NUMBER
Error text
In the test, the error messages are displayed in English language. The
following is an example of the display of an error message at the user
display:
TEST POS NV-RAM 01
ADDRESS ERROR
ANY KEY TO CONTINUE
Static errors are accurately localized with the POST, though sporadic
errors can be determined only to a limited extent.
If POST signals an error, please contact your appropriate technician or
Customer Service. Below you will find a list of MS-DOS critical errors and
the POST error messages.
