During upgrade my HP DL360 G5 ESXi 5.0 u1 hosts to ESXi 5.1 I received a purple screen with warning message:

 

The system has found a problem on your machine and cannot continue.

VMware ESXi requires the Execute Disable/No Execute CPU feature to be enabled

 

Solution:

Restart the host, press F9 to boot in BIOS mode

Advanced Options > Processor Options > No-Execute Memory Protection, then configure: Enabled

  1. Thanks for the guide, worked perfect!

    I just got two HP ProLiant DL380 G5 servers, updated the BIOS to 05.02.2011 version and did as you wrote in guide.
    Installed VMWare ESXi 5.5.0 with no problems at all 🙂
