Ok friend,
I will give a look !
Your Eeprom is Write Protect = Error 280 not reflashable !
We can try only using Recovery Method, then only HW SPI Programmer
can rewrite this Bios Mod !

Here there are two locks :

Hi guys,
i need to enable the Intel VT on this an Acer Extensa 2510.
The system bios version in 1.22, and the InsydeH2Ois the rev. 3.7.

To help you helping me, in the Acer support site (http://www.acer.it/ac/it/IT/content/drivers) there are many BIOS files, but I don't know how to use those, and if they are right to solve my problem.

Hi,

I checked bios 1.26

Setting: VT-d, Variable: 0x1EB {05 91 FA 02 FB 02 FA 00 34 12 EB 01 10 10 00 01 00}
0x5296D Option: Disabled, Value: 0x0 {09 07 23 00 00 00 00}
0x52974 Option: Enabled, Value: 0x1 (default) {09 07 24 00 10 00 01}

It's enable by default...

Can u get 1.22 bios or backup ?

[nannib80]

Hi!
Thank you for your help..
In the official support site i din't find the 1.22 BIOS, so i tried to backup with "Backup_Tools.exe" (http://rghost.net/58219938?r=2966).

Here there are my results: https://www.sendspace.com/file/js2puu

I'm also including two screenshots of the BIOS.

But there is a problem: you're talking about intel VT-d

Setting: VT-d, Variable: 0x1EB {05 91 FA 02 FB 02 FA 00 34 12 EB 01 10 10 00 01 00}
0x5296D Option: Disabled, Value: 0x0 {09 07 23 00 00 00 00}
0x52974 Option: Enabled, Value: 0x1 (default) {09 07 24 00 10 00 01}

, that is made to directly use peripheal devices. [Virtualization Technology for Directed I/O" (VT-d), as wikipedia says]

What I need is Intel VT-x, to enable virtualization of 64bit machines.

[pombas]

Your cpu supports it, but on intel don't support VT-d something is wrong...
http://ark.intel.com/products/81016/Inte...o-2_70-GHz

I looked at your backup bios and didn't find any VT-x

[nannib80]

This is the story..
I only wanted to virtualize Mac OS X 10.10 Yosemite.
Because today I finally made that, I think that the Intel VT-x is already enabled.
And as it was hard to me I thought that Intel VT was not enabled.
So thank you Pombas for your help.
Just a question.. Which software did you use to look at my BIOS backup and to the Acer 1.26 BIOS update?

Used this:
Phoenix Tool
Universal IFR Extractor
