AES Instructions (encryption)/VT-d (Hyper-V) & Peripheral Power problem (BIOS)

Question

Hello
I've just purchased a Z86A-G65 G3 motherboard with a i7 2600 CPU. Both parts is supposed to support VT-d for Virtualization and AES hardware acceleration for encryption.
I installed Win 2008 R2 SP1, and set up my Raids with AES encryption. AES instruction set was enabled. Truecrypt detected the support. Then I installed Hyper-V and a guest OS with a Domain controller. Added the Host machine to the domain, and now Truecrypt does not use the AES instruction set. It can not see that the CPU/motherboard supports this.
So, my question is: Is there something preventing me from running both VT-d and AES instruction set at the same time? It's the only thing I can really think of.
My second problem is that I can no longer get into BIOS! And therefor can not check the AES instruction settings or Hyper-V settings, to test tings. The power for my PS2 and USB keyboards is turned on a few seconds to late, so I can only interact with the Marvel SATA bios and beyond. Not the POST. I've tried several keyboards (5) and it's the same with them all. A couple of seconds to late to power on. I was able to enter BIOS earlier when I first installed the hardware, no it's impossible. Only thing I remember I might have done, is to remove the startup Picture/Logo. I've cleared the BIOS, but the situation is the same. The power comes exactly to late.
What are my options?

After 2 hours of cursing, I found a solution though:
- Remove battery from MB, keep it away till the power is completely drained. Shortcut the pins under the battery position for a faster drain.
- Place the battery in the battery holder again, but do NOT push it down in it's place. Only make it have contact with the metal, to be able to power up the MB.
- The power button on the MB will light up when you got connection. After you have powered up the MB, remove the battery IMMEDIATELY.
Before the OS boots, you'll be presented with a few CPU and RAM details. Under this details, you'll be presented with the BEAUTIFUL message: "Press F1 to enter setup". Tada!
This have been a real struggle. One star less to MSI for this one.
What you did was a thorough CMOS Clear.  That also means that when you did this:

I've cleared the BIOS
Something did not go as expected.  The whole point of a CMOS Clear is to make the system completely powerless.  Was your PSU connected to A/C power when you originally cleared CMOS?  It needs to be disconnected and the power-on button has to be pressed a couple of times (to drain capacitors) before the CMOS-Clear Button at the back panel should be pressed for a couple of seconds.  This procedure should always yield this:

"Press F1 to enter setup"
If that did not happen when you cleared CMOS before, then there was either still power in the circuits when you pressed the button, or the Clear CMOS Button is defective.
