Hello Mats,

I think I didn't really get the point in your statement.

"please wait until the processors are available"


What processors are you talking about?! My AMD AM2 3600+ X2 (65nm) already has the AMD-V feature, right?!? And the Mainboard already has turned off this AMD-V feature, but I want to turn it ON again, right?!

So, what do I have to do to get HVM support? New CPU? New Mainboard?? Or should I completely switch to Intel Core2Duo?

I am completely irritated now :-p

Yes. Some manufacturers actually do this (especially

possible a bios upgrade will reenable the option.
Are you sure manufaturers can disable this for AM2-boards?
For intel its well known, but for AMD..

I'll probably be told off for explaining this :-(

Without going into "secrets", yes there is a way to "turn off" AMD-V
with the BIOS, and no, you can't ask for more details unless you have an
NDA with AMD. It's also not possible to "re-enable it". Although the
BIOS _SHOULD_ allow the enabling/disabling to be "user selectable".

Future versions have a more well-documented way to do this. Again,
unless you have an NDA with AMD, please wait until the processors are
available, and there will be more details available to everyone.
