Request to unlock advance features in Acer Aspire 5740 Bios Phoenix 1.28

[Rainer]

Thank you so much for the modified bios.

I tried to flash and got an error "new BIOS image size doesn't match current system BIOS size error code -200" any suggestions?

[belog]

will this work for a acer aspire 4755g?

Please remember to post the results (pictures if possible) of the BIOS flash. As I could not emulate this BIOS, this is especially important.

Hello,

Unable to flash this..., used Winphlash, but it gives me an error:
Corrupted interface descriptors in the new BIOS file.

I have an acer aspire 5740G, I only need to enable virtualization, so I can study for an exam...

Hi BDMaster and bios-mods,

I am an Acer 5740g owner with the latest 1.28 bios file.
My Acer is running windows 8.1 x64, and I have smashed into a big wall, "virtualization".

As my work involves a lot of visual studio 2013, and windows phone testing, I have decided to learn some serious programming in c#, as I cannot afford a more suited laptop (similar to the workstation I have at my workplace) and neither a windows phone 8.1, I would really need the bios unlocked, up and running with virtualization.

I have read the entire 3 pages from which I have tried one bios file still available in page 1. But with no success.
The steps that I have followed are:
1. renamed the bios.wph to "JV50128.WPH"
2. Launched as an administrator "JV50128.exe" by Winflash method.

Outcome:
The flash is successful, windows is restarted automatically with no unlocked options what so ever.

Here is my bios link: BIOS 1.28 A_A

I am serious and I will provide as much details as I can, I just need some guidance and if necessary an unlocked bios with virtualization.

Btw, the last two files hosted in the rghost.net are deleted

Happy new year,
Eugen

Hello eugen88,

Have you tried flashing from DOS?


Happy New Year,

Spot on,

Made a bootable memory stick with RUFUS using the FreeDOS option available there, dragged and dropped the FLASHDOS.BAT + the rest of the required files and voila it worked like a charm

Now I can emulate windows phone without a problem.


Thanks, Steven and overall thanks bios-mods.

Cheers and a Happy New Year,
Eugen

hi

does anyone know if it is possible to unlock the menus to overclock?

I just wanted to stop in and say "Thank You" to the dude that came up with this bios hack. It just royally saved my butt after replacing the CMOS Battery and repasting the CPU. My 5740 was showing the processor as 1 core, 1 thread. The CPU Control Sub-Menu was what I needed! Whatever Acer uses to fix this issue, they charge $100 to do it (if it's still under warranty).
