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

[DetlevCM]

Hi Guys,


I have used this information to enable VT on my Sony SZ38GP using the method and registered described here (354) quite awile ago.

I have an application which would take good advantage of Hyperthreading, however i don't have an option to enable this either. I read here that user bogart has found the token to enable HT as well for this BIOS. I hope somebody can share the information for this token as well !

Thanks

Chris

??? Hyperthreading need an processor that supports that.
As far as I am aware the processors in the SZ don't.

Hi ,

Mine has a T7200.

If I check the Intel Site, I get:

Status Launched
Processor Number T7200
# of Cores 2
# of Threads 2
Clock Speed 2 GHz
L2 Cache 4 MB
Bus/Core Ratio 12.0
FSB Speed 667 MHz
FSB Parity No
Instruction Set 64-bit
Embedded No
Supplemental SKU No
Lithography 65 nm
Max TDP 34 W
VID Voltage Range 1.0375V-1.300V
1ku Bulk Budgetary Price 286.00

So I wonder if 2 Threads are per Core or per IC. Hmm, maybe it should be 4 if per IC. Maybe I misunderstood this ?

EDIT: Ok, pls forget my question, I found the answer : Intel® Hyper-Threading Technology : No

I could enable VT in my VGN-CR220E (BIOS R1121Q0) editing line 05BB.

Thanks for the instructions.

By the way, it wasn't necessary to reboot between creating "Default.txt" and editing it to "Modified.txt".

Added to the master list.

Hi all,

trying since days to enable my hardware virtualization on my Sony Vaio VGN-N21E (yes, it is very old ) becouse I need to work with VMWARE workstation 7 and some features are disabled since VT is turned on.

I'm a tech operator, so i'm a little bored of limitation like this, please, help me
to understand how to enable it with symcmos. My bios is R0070J4 (12/06/2006)
and REALLY can't find any support on Sony Vaio website or any way to update my bios (Phoenix one).

Already tryed to enable :

- reg 0195
- reg 0318

with no success (securable test).

How can I find my correct reg. point without brick my office laptop (really don't want to disassemble it) ?? There is any matematical method ??

Bios infos:

( SYMBOLIC CMOS EDITOR - Version 643710-032 )
( BIOS Version: NAPA0001.86C.0056.D.0612061953 )

dumped bios file from symcmos attached below:

BIOS.TXT

CPU-Z DUMP

txt file
cpuid-report.txt

htm report file
cpuid-report.zip

Please help me, really need it to continue working with this, not-so-cheap, laptop ...

thanks for support

Pretty much everything we know is contained in this thread. If your machine is not shown in the master list, you'll need to refer to the initial instructions on how to try to find the register. But there is no guarantee that you won't brick the machine in the process. Or at the very least need to open it up and do a hard reset. That is just a fact of life in this.

@lovelord,

VGN-N21E come with Intel® Core™ Duo Processor T2250 which don't have VT capability.

Regardless VT is locked or not by BIOS, if the CPU support VT, Securable will report VT = YES.

If it is not available, why securable report "Locked Off" ?

I think kizwan is mistaken - it says locked off because that's the BIOS setting on the Vaio - it would say it is not supported if it weren't.
