NX bit control GA K8NS 939-Ultra

[mcbloggs]

I have the above currently redundant motherboard which I'm hoping
to put Win 8 on. The specs are completely adequate for this purpose
but the bios does not allow me to enable the NX bit as there is no
advanced settings for the CPU. The default value is 0.

I have investigated the appropriate AMD documentation and I believe
that all I need is for processor initialisation by the bios to enable
this bit. The register is the EFER register and NXE is controlled by
bit 11. The appropriate documentation can be found on page 368 of the 'AMD
Hammer family Processor BIOS and Kernel Developers guide'.

This register is already accessed during set-up I'm sure as for example
long mode is controlled from there. I don't need the advanced settings
screen, Just this bit set on.

Hoping you can help. I'ld be more than happy to supply a contribution if
a working solution can be found.
