  Service hints & tips

Power-On Self Test (POST)
When you power-on or re-boot the computer, the computer runs the following two power-on self tests (POSTs).

Note
These tests are run consecutively without intervention.

BIOS Code
(resides on the system board)
Checks the memory, system board, direct access storage device (DASD), configuration, etc.. If you receive a POST error from the BIOS code, refer to the "Symptom-to-FRU Index (Micro Channel)" in the PS/2 Hardware Maintenance Manual
Licensed Internal Code (LIC)
(written to files on the hard disk drive)
Checks the P/390 processor card and attached memory card.



If you receive a POST error (165) from the P/390 LIC code, see "Error Reporting (P/390)" in the Hardware Maintenance Manual.
