wagDj,
I have same BIOS version and this will be my last Sony VAIO.
I already called Sony for so many times and the answer I get is "Sony currently does not support Virtualization but check for the future BIOS release". I hate Sony .... no drivers for x64 OS + VT = "Dont buy Sony"
Anybody out-there can help us pleaseeeeeeee.
Thanks
What do you know about BIOS NVRAM hacking?
Let me add my $0.02 to the jar. To enable VT on Fujitsu-Siemens Amilo Pro V3505 with latest (and probably the last) BIOS v. R0G - which isn't offering VT support despite some relevant strings in its string section, set following tokens in NVRAM to 0001 (I used symcmos):
258 - this is the flag which enable VT support (that is, enable following flags to work); "symcmos -L" doesn't list it, one'll need to add it to LITERAL.TXT
25B - this one is VT-x enable flag; "symcmos -L" lists it
If you want to get VT working on Amilo Pro V3505, you need to set both flags to 0001
also there is token 279 which corresponds to bit 1 (mask 0x2) of MSR 0x3A, apparently this is VT-in-SMX support enable. Of course BIOS doesn't offer any means to turn this on and "symcmos -L" doesn't list it; I didn't touched this one but maybe it'll be useful for somebody.

Hey,
After reading this thread for a while, I began poking around in the code of my BIOS, and found this in BIOSCOD6.ROM, at offset 0xCCAB:
Phoenix BIOS winphlash image filename: BL50360A.WPH (V3.60)
Laptop model: Acer5633 WLMi
With the symcmos utility I could control the 0x312 bit, so I tried setting it to 1, and it enabled VT-x.
Thought I should post this information here. It might just help someone someday.

mov ecx, 0x3a ; MSR 0x3a
rdmsr ; read the MSR
mov ebx, eax ; save low-order 32-bits of the MSR value

jz skipVT ; skip enabling VT if token at offset 0x30f equals 0
mov ax, 0x312

wrmsr ; write the MSR

Hi guys,
Thank you so much for the information provided in this thread. With it I was able to enable Intel Virtualization Technology on my Acer Aspire 9420.

Also thank you to bughunter2, because of his statement, I was able to narrow down to the address which I need to set with 0001.

You're welcome.
I'm trying to enable VT-x ..
Model W220R ( Phoenix BIOS 1.10H ) / CPU is Intel T2130
after backup/disasm bios Ifound this code in BOISCOD04
So I think 0x636 is my NVRAM addres of VT-x enable
But after update NVRAM computer failed to start, (i repair it with batery remove recovery)
What else to do... ??

Please go to my thread to learn on how to locate the exact address. The link to my thread posted on my previous post.Apoxioman wrote:I'm trying to enable VT-x ..

Hello everybody!
Thanks to you guys and the thread over here http://forum.notebookreview.com/sony/18 ... aptop.html based on your work I managed to enable VT on both my VG-AR21S (upgraded to T7200) and my VGN-AR760U (T8100)... So far so good.
One thing that has been bugging me about my VGN-AR760U is the lack of RAID support... I believe there is a register set, which disables RAID ... but I do not have the slightest clue how to figure out, which register this might be...
Can you help me?!?
You can grab my bios package here: http://www.mediafire.com/?t0u6owdcahksd3e
I build a flashable version of my R2080J8 bios using a backup bios incorporating the platform data from R0032J8 with a hex editor...
