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

[Sml6397]

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).

You are welcome!

I am glad that this BIOS mod has helped you.

I would like to thank the brilliant mind(s) behind the modded bios. I have an aspire 5740-6378 that I flashed this bios onto, and it works well, stable, no errors or kinks of any kind so far. I would like to ask, would someone be able to add some overcloking features to the bios? such as FSB,VTT, DRAM and any other available tweaking options the bios may have.
Thank you in advance.

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

Hi Newchamp, did you ever resolve this? I get the same result flashing using Winphlash when I try the modified BIOS. I have an ACER 5740 64bit running the standard ACER BIOS v1.28 - I didn't try the DOS method yet from a USB stick. regards, kwick

Good morning,

I've this laptop model (Acer Aspire 5740-5255) with this BIOS mod 1.28.

Recently I bought a caddy hdd for this laptop and I installed Kali Linux 2.0 in an SSD. In the primary disk I've installed Windows 10 x64.

Windows show me the SSD in "disk manager" but, when I try boot from the SSD with F12 key, the laptop show me "operating system don't found"

Can anybody help me? Thanks in advance!

Hello vishalagarwal1286 & h35am,

The BIOS mod is complete! You can find the modified BIOS image at the bottom of this post.

Mods performed:
• Added an Advanced Menu
• Disabled the function that may have been hiding the INTEL Menu

As PBE (used to emulate BIOSes) could not emulate this BIOS, I was in the dark when modding. Further mods will require pictures of the BIOS menus so I know what is showing up and what is not.

Generic Warnings/Disclaimers:

Please remember to take proper precautions when flashing your BIOS. Even if the image is safe, the flashing process can still fail. Make sure that (if applicable) your notebook is fully charged (100%), the power plug is properly connected, and that the chance of the power going out is as minimal as possible. Do not interrupt the flashing process. If possible, it is a good idea to have a working CRISIS recovery disk when messing with your BIOS. Use the flashing instructions for your particular computer brand. DO NOT DO ANYTHING UNNECESSARY!!!

I take absolutely NO responsibility for ANY damages that may occur to you, your computer, your personal belongings, your neighbor's cat, or any other personnel or equipment as a direct or indirect result/consequence of your, or any one else's, use or misuse of any of the files that are in this archive at the present or at any time in the past or the future. You assume full responsibility for any damages or inconveniences that may occur by choosing to flash, or otherwise use or misuse, this image or any of the other files within this archive.

Have fun!

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 fsugarray,

I have the 5740G and I flashed in DOS the bios without issues.

Cheers,
