btw I've updated my previous reply above regarding mux

I saw, but isn't it a common graphics device switch?
Please, try my second BIOS mod: fyrplay EXTRA.zip. Locate additional menus in the Main tab.

And also System Diagnose.
Anyways, nice news. Thank you for the test. But let's take the last step and try to fix the reboot bug: fyrplay EXTRAS.zip. It happens because I mixed up some values.

What i'm trying to achieve is access to overclocking settings user Thats1947 requested.

This is the only photo I wanted to get. I recommend not to get carried away with setting parameters from this menu, because it is just as dangerous as changing the primary graphical device. Regarding to System Diagnose, it seems that for this reason the menu was originally removed by the manufacturer.

I think this was the final version. I meant, this one I uploaded is for another user. Do not flash other user's bios.

Thank you too @Sweet Kitten for unlocking the options.

Also if i want to go back to the original version what should i do? The installer from Acer errors out.

Wait so someone with the same spec laptop shouldn't flash this on theirs?

There are two options. I can modify BIOS updater from support page or you may take the bios region file from "results20.rar" archive and replace the one that is from bios mod archive I sent you.

Everything is simple: DMI data of your device will be replaced with data from someone's BIOS in this case. DMI contains serial codes and other unique stuff.

The 2nd option seems better, should i also replace the vars file with the one i shared first or just use the current one from the last bios zip you shared..

If anyone else has a modded bios and changed the wrong settings and now your laptop wont boot properly. You can download the official bios from acer website and extract the exe with universal extractor. Look for a abobios.bin file and drag it to a usb drive formatted to FAT32. Rename it to C5PRHX64.FD With laptop turned off hold down Esc and Fn and turn on laptop with letting go of Esc and Fn. Fans will spin loud and bios will begin flashing. Laptop will automatically reboot.

That's not the right name for PH315-54-XXX, its...

1
 
GH53Gx64.fd

Follow these steps to recover ...
1. Extract the bios file abobios.bin from the BIOS Installer from Acer and rename it to the above written name, make sure the extention is .fd and not .bin & the size of abobios.bin shouldn't be more than 38694960 bytes.
2. Format a USB drive to FAT32 and copy the renamed bios file inside the drive.
3. Connect the charger to the laptop and keep it connected to power until the whole process is complete.
4. Connect the prepared USB drive to the laptop.
5. Press & hold ESC + FN key and press Power Button to turn the laptop ON and let go of ESC & FN key.
6. Within seconds the fans will spin at max speed and after a while it'll detect the file inside the prepared USB drive and flash the BIOS.

Process can take upto 10 mins so have some patience & don't panic. Once it's done it may not reboot automatically so disconnect the charger and press the power button on the laptop, you'll see the laptop's keyboard light up again and again few more times and finally it will boot fine.

Thanks @Sweet Kitten for the proper name

Doesn't work. The fans spin at max speed but the laptop reboots after a few seconds.
