ProLiant G6 and acpitabl.dat

Had recently an ProLiant DL370 G6 which had an installed Windows Server 2008 that stopped working after doing HP Updates.

I had the following symptoms:
– Windows  is booting forever in the splashscreen
– in Safe Mode Windows stopped at “acpitabl.dat”
– PXE Boot was very slow – about 5 seconds reaction time between Keystrokes

After changing all Hardware, including Network Card and Array Controller P410, HP Technical provided us with the solution:

The Array Controller need to be placed in Slot 7 (it was in Slot 2) AND we had to clear the NVRAM (this is switching a dipswitch as shown in the Manual of that System)

Changing the Array Controller rendered Windows usable again, clearing the NVRAM recovered the PXE function useable :)

Hail to the King ;)
