Post Execution Flow - NEC N8100-1575F User Manual

POST
POST (Power On Self-Test) is the self-diagnostic program stored in the system memory.
When you power on the server, the system automatically runs POST to check the mother board,
ECC memory module, CPU module, keyboard, and mouse. POST also displays messages of the

the server beeps for many times between power-on and OS start-up.
an error message appears on the display unit.

The following describes the progress of POST in the chronological order.

installed optional board. Make sure to read the manual that comes
with the optional board before any key entry.

PCI board or moved it to another slot, may display the message that
indicates incorrect board configuration and suspend POST.
In such a case, press F1 to continue POST. Board configuration can
be made using the utility described later.
