Sony Vaio Z2 (2011) Advanced Menu BIOS Hack

[Encephalartos]

Hi I have installed the hacked Bios from “camiloml” and I am wondering if there is a way to revert back to the original Sony bios? Because I need to send my vaio in to Sony due finger print reader problems. My laptop was running R2085H4 and how would I flash it back? I have posted this into the SA hacked bios but maybe you guys would help? I have just used the flash by pyr0 but need a copy of the original R2085H4 from Sony. and when I download it from them it just say my bios is current

Hello i have a Z21 with a Core i5 2410M

On the Intel Page
Intel® Core? i5-2410M Processor (3M Cache, up to 2.90 GHz)

is written that AES-NI ist not available, but at the bottem of the page is written

"Some products can support AES New Instructions with a Processor Configuration update, in particular, i7-2630QM/i7-2635QM, i7-2670QM/i7-2675QM, i5-2430M/i5-2435M, i5-2410M/i5-2415M. Please contact OEM for the BIOS that includes the latest Processor configuration update."

so it should be possible to function with a modification in the bios right?
I've flashed the new hacked BIOS but i didn't find a option to enable it.

Are there any ideas or plans to enable this feature?

As far as I know, AES-NI are enabled by default. I can confirm this is the case even for the Z2 predecessor, the Z1.

Hi!

Just had the time to flash the new BIOS (BTW: every time I update the BIOS, the fan goes to the maximum speed before switching off, and this makes me a heart attack!! )

Anyway: I would like to know which ACPI setting is recommended. I see ACPI1.0B, ACPI3.0 and ACPI4.0. I would set 4.0, but does this implie some new setting in the operating system?

pyr0, A few questions, what model is your Z2?
Another question, are there any options for disabling AHCI? And which things exactly in the hacked bios should I change to disable it? I'm just asking these before I try my luck with the hacked bios.

I need to dual boot 7 and XP for work purposes. I slipstreamed the SATA driver from the website into the installation but received a BSOD in setup. After googling the error code it appears to be AHCI settings in bios

Is AHCI crucial for the SATA/Raid/etc to work?

I'm just wondering if Sony has support for Windows XP on Z2 and even has downloadable drivers how come it can't install XP.

Larz9220, are you asking to me?

[Larz9220]

Sorry, I should have clarified, I was asking pyr0 the author of this thread and how their bios hack worked.

Hi,
I cannot install your version because my bios was upgraded via "vaio update", so when I try to install your version, I have a popup with:
"This bios is already up to date. ..."
I can't find the previous version of the bios so can you help me ?

Thanks.

I'm having the same problem, is there anyone who knows how can I solve that?

This could be your answer :

To do the install I had to execute:

InsydeFlash.exe BIOS_VERSION.rom
