[REQUEST] Acer Aspire 5750(G,Z) & 5755(G) BIOS Unlock

[istiaquechoudhury]

Hi,

Please can I request a UNLOCKED BIOS s/w for:
UK retail
Acer Aspire 5750G
Running Windows 7 64bit
Insyde H20
BIOS Version 1.21

The BIOS was flashed from within windows via Acer's tool and specific BIOS version here:
https://global-download.acer.com/GDFiles...1528224156

I have attached all screenshots of my BIOS for reference.

Please can anyone confirm if the unlocked BIOS will finally allow 16GB installed to show and not capped to 8GB (memory is tested good individually).

Thanks and of course a donation will be made after successful testing

Hello, I have installed this bios in an Acer Easynote TS11 HR 240SP. Everything works fine except that every day at the first start, I do not recognize the HDD. I have to press CTRL + ALT + DEL, to restart it and then if it recognizes it. Can somebody help me?

Sorry for my bad English

Can I request a mod of bios 1.21. I would like any overclocking enabled either through bios or xtu. Even just being able to adjust the base clock would be great. Currently using modded bios 1.21. I have an acer aspire 5755 and running uefi windows 10.

Thank you for all the work you have done.
