How to Enable Intel VT and AHCI on a Napa/Santa Rosa platform Phoenix BIOS Vaio laptop

[bernd75]

I'm wondering if it is possible to use the Intel-AMT.
If I'm not wrong, then it was a requirement to have VT enabled.

Hello there,

I don't know what you mean, You say:

change the register of your model from 0 to 1

What do i need to do? I don't understand.

I have a Vaio FZ21Z and I want to enable hardware virtualization. I found elswhere the settings for my model:

VGN-FZ21Z R1120J7 reg 02CD.

So do I change it to 12CD?

Thanks

No, check out the sample table that's attached in the first post. After generating a symbol table with symcmos from your own bios, you'll need to change the value located at 02CD (search for this in the table) to 0001 and update the nvram with this modified table.

Guys, does also include SZ280P? I'm not sure if my older generation of SZ has VT or not.

Thanks

Yes, your SZ280P (Napa version) supports VT as long as your CPU supports it as well. You can update the BIOS to R0112N0 then follow the rest of the instructions.

Hi! I have and Vaio VGN-FE28H. This laptop has a core duo without VT (from factory). But I've changed the cpu by a Core2 T5600 with VT. And I have the bios problem. My bios version is: R0174J3. How can I find the correct register to change? Thanks and sorry for my poor english!

Another one for the list:

VGN-TX3XP/B - R0034N3

VT-x: (03a2) [0000] ---> (03a2) [0001]

I don't care for AHCI, so...

Thanks for your reply. I managed to follow your instructions, but i am afraid it is not working. Here's what I did:

Started up using Hiren's startup disk
enabled NTFS
went to my c drive
started Symcmos
dumped the cmos
edited it to 0001
saved
checked if it really did it and it did
write it to nvram which it said was working

After that i have no result. VT is still disabled. I have no idea what is going wrong here. Can you help?

Does anyone know how which symbol one would use on the SZ to allow overclocking of the nvidia gpu? (I know that the laptop might get hotter than desired.)

hi, Killerzac

Can you do same with the bios R3041Q0 for the CR520E?
Thanks in advance!

The register definitely seems to be correlated with the firmware number which makes sense.

I haven't seen anyone post any success with BIOS version R0091N7 (which I have on my TZ31). Anyone had any luck with this one? Also, does anyone know how I could dump my BIOS, in order to be able to disassemble and take a look for myself? I'd rather look into the code and find out for sure rather than just plugging values as I don't want to have to pull this laptop apart if I get it wrong.
