The keyboard/mouse controller has a built-in Power-On Self Test, and the 
firmware checks the result. If an error is detected, an 8-digit error code is 
displayed. The error is written to the Error Log, and the system continues.

The SCSI POST opens the adapter and runs several test scripts that check 
and exercise the various functions related to the chips on the integrated SCSI 
adapter, such as DMA, simulated mailbox commands, and so on. If an error is 
detected, an 8-digit error code is displayed, the error is written to the Error 
Log, and the system continues.

The SMS programs make it possible for you to view information about your 
computer, run memory tests, and set the device from which the server will 
boot.

By default, the firmware uses the serial port S1 to display logos, messages, 
errors, and also as the interface to the SMS programs. If a supported 
graphics adapter is installed in the machine, the firmware will redirect the 
output to this adapter instead of the serial port. This means, if you have 
installed a graphics adapter but you want to use an ASCII terminal attached 
to serial port S1 as the console for the SMS programs, you will have to 
remove the graphics adapter first.

The SMS programs provide two types of interfaces: a graphical user interface 
(GUI) that can be used on a graphical display and an ASCII interface that can 
be used either on an ASCII terminal or on a graphical display.

Note: The ASCII interface provides more functions than the graphical 
interface.

The 8-digit POST error codes are listed and described in the Service Guide 
for the corresponding PCI-based RS/6000 system:
