How do I enable VMX?

Following Bryan's guide, I managed to get Debian running on my MinnowBoard. Unfortunately, I'm stumped again when I tried to get KVM working. Both ark.intel.com nad /proc/cpuinfo says that VT-x is supported, but dmesg prints "kvm: disabled by bios". I poked around the EFI shell a bit and I couldn't figure out how to enable VMX. On other UEFI motherboards usually I need to exit EFI shell and configure it from a different screen, but on the MinnowBoard exiting the shell just restarts it.

In case it's relevant: my Debian install deviates from Bryan's guide somewhat in that I'm running wheezy but with backported 3.10 kernel from sid.

Hi Julian,

Unfortunately, the firmware does not support VT-x. Let me work with our firmware engineers to figure out when this can be supported in the firmware.

Thanks…elmer

Just a quick follow-up: I installed UEFI Firmware v1.00 today and KVM now works.
