Xen on intel DG965RY motherboard

[Mayuresh <mayuresh%acm.org@localhost>]

On Intel DG965RY machine running NetBSD 6.1 i386, xentools 4.1 DOM0
kernel, DOM0 boots fine, though when trying to create an instance, get an
error that the hardware does not support virtualization.

Following is the processor information.

vendor_id       : GenuineIntel
cpu family      : 15
model           : 6
model name      : Intel(R) Pentium(R) D CPU 3.00GHz

fpu_exception   : yes
cpuid level     : 6

Searching around tells, the option needs to be enabled in the BIOS. But
the BIOS does not seem to have a relevant option.

The BIOS version is of 2007 and there seems to be newer version of 2009
available for download. While I am not sure whether upgrading the BIOS
would help enable virtualization, I can take my chances - of course,
unless someone readily knows it won't work.

Now the question is, how to upgrade the BIOS. Intel provides DOS/Windows
executables for bios upgrade.

Trying to run the DOS executable using pkgsrc's emulators/dosbox gives
"port mapper table signature not found" error.

So in short:

- Is there any way to get a ready answer to whether Intel DG965RY
  motherboard would support xen - after upgrading BIOS?

- Would appreciate any help in flashing the BIOS using NetBSD.
