Acer Aspire 7540G { Unlocked BIOS in post #13 }

[Sml6397]

Hello xir98,

Try looking at the "bottom" of the motherboard for the area where the CMOS battery is. Usually, the BIOS chip is located somewhere in this area. Most of the time, the "top" would be where the CPU and fan(s) are.

This is from my experience, but may or may not apply to your computer.

Hi friend,
on Acer site there is only two models Aspire 7540 and G versions and They have same MoBo so
same Bios !!!
If your is a 7540 or 7540G You have to use the original Acer version 1.11 and the can use the
Ahmed Hossam Modded version (2nd new vesion !!! as 1st Brick laptop !!!)
If your Bios is just updated to 1.11 You can flash the Modded One without update original.
Regards

Hello first thanks for your fast reply, i never have flashed a phoenix bios so the mod.rar in #13 have 2 files : Bios.wph and Bios.rom

But here in the bios tutorial here https://www.bios-mods.com/bios-update/ i cant find the way to flash them. Also looked in the thread and nothing posted about how to flash them. thank you.

Hi,
I have Acer 7540g and I would like to flash bios because I need Advanced Tab in Bios menu. I want to disable bios shadowing but I have problem "how to flash bios?". I have flash drive with crisis tool, I put there bios.wph, minidos.sys and phlash16.exe and I don't know what next. I try to use Fn + B button, also combination like Fn + Esc or Win + B but nothing works. Any idea how I can resolve my problem?

I flashed it today succesfully by using Phlash1416 on this thread and MOD.rar from #13

in a 32gb pendrive. Flashed MSDOS from rufus. Then moved files contained in mod.rar
lbooted from usb. MSDOS ready.

DIR

Then launched the command Phlash1415 bios.wph

Waited and bios unlocked
