FYI, if you do this, various virtualization technologies may not work 
right, especially for 64-bit guests.  You may or may not care in the 
context, and I understand that "working" is better than not, but just 
FYI...  Perhaps there is a different solution post-install, or if this 
is needed.

For example, I was trying to run VMware Workstation 7.1 on an old Dell 
PE-850, but I was unable to run 64-bit guests even though the host OS 
was 64-bit, because the CPU lacked the VT feature.  But turning it off 
in the BIOS will have the same effect.

Having said all of that, I'm a bit hazy on the difference, if any, 
between "VT" and "VT-d"...  YMMV.

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
