Re: ESXi 5.1 install error on Intel Q9450

Hello,

Have you checked all CPU features from ESXi Hardware Requirements?

See link below:

VMware vSphere 5.1

For example:

ESXi 5.1 requires the NX/XD bit to be enabled for the CPU in the BIOS

ESXi 5.1 supports only LAHF and SAHF CPU instructions.

Hope will help.

Yours,
Mar Vista
