Hello

I tried doing this with my G750JH. Downloaded bios 206 (latest), modified with AMIBCP 4.53, and tried to flash it. Nothing seems to work. Winflash claims that the bios is both too old and the file is invalid. Easy flash accessed from BIOS claims the file is too old, FTK cant get write acces to BIOS, and when I try the crisis flash option you descibe the USB-drive flashes whilst everything else remains dark, but after about 20 seconds the laptop boots normally.

I've tried naming the updated bios file amiboot.rom, amiboot.bin, G750.bin, G750JH.bin G750JHA.206 (original name) - nothing seems to work.

Any ideas?

Hi there.

I have an Asus G750 JW and I see the BIOS options are kinda limited.

Not looking exactly into overclocking my video card, I'm more into Thunderbolt options enabling to play with my eGPU configuration, but don't mind maybe some extra stuff like CPU overcloking or memory timings.

So, I downloaded latest ASUS G750JW Bios ver 208 (from their website) and opened it in AMIBCP 4.53.

Then tried to make small changes to some values, like I've seen an option : Speaker Volume with an optimal value 4. I change it to 5 and save under a new name.

Binary comparing the files shows 1 or 2 bits to be changed and also some big changes (I was expecting only 1 or 2 bits to be changed) in some part of the file which makes me wonder if I should attempt to flash the result.

Also, tried to just save the file without any modifications applied and it still not producing an exact match of the original file, got a different block in some part of the ROM file.

So, can anyone provide some help on this matter?

What steps should I do in order to mod my BIOS?

Lastly, I've read on the asus forums that some sort of recovery would be possible if keeping the CTRL+Home button pressed I turn on my laptop while a USB stick with a bios filename is connected.

While Ctrl+Home is doing indeed something (like 4-5 seconds of thinking on a black screen) can't trigger the recovery procedure despite trying several filenames like G750JWAS.208, G750JWAS.ROM, G750JW.ROM, G750JW.BIN or AMIBOOT.ROM. Any ideea on this matter?
