HP Z400 Workstation - Workstations with Specific Processors Fails to Maintain Intel Hyper-Threading (HT) Technology Settings

Release date : 18-Jun-2009

Last updated : 25-Jun-2009

DESCRIPTION
Workstations configured with the processors mentioned in the SCOPE section, fails to save Intel Hyper-Threading Technology settings.
By design, the HP Setup Utility (F10) does not save BIOS settings for capabilities not supported by the processor installed in the workstation. For example, if Intel Hyper-Threading Technology is enabled by the user in HP Setup Utility but one of the processors mentioned in the SCOPE section is installed, the settings will automatically revert to Disabled after exiting the utility.
