[REQUEST] Acer Aspire M5-481(G,P,T): BIOS Unlock
#1
Putting this request out after exhausting every other option, including attempting it myself.
I've seen this request in a few other places so I think it would get some good use.

I would like the ability to increase the base clock of the GPU (640m LE) to 900mhz.
Apologies if I'm missing any information.

System Manufacturer : Acer
System Model : Aspire M5-481TG
BIOS Version/Date :- 1.12 , 12/17/2012
bios download link :- http://global-download.acer.com/GDFiles/...ER&SC=PA_7

Hi everyone! I'm new on the community!
I have a problem I can't resolve by myself. I'm trying to turn my Ultrabook into an Hackintosh and everything is almost fixed and working but there is still a bug. I can't change the RAM I dedicate to my GPU. Since Chameleon/Chimera only allow 32/64/96MB of RAM and my computer is locked to 128MB, graphics aren't working.

My BIOS is an Insyde BIOS. It's a UEFI and legacy BIOS. I honestly can't tell you which BIOS is the good one, there are two available on Acer's website (http://www.acer.ca/ac/en/CA/content/drivers » Ultra-thin » Aspire M5-481T)

My laptop is brand new so I want something stable and that won't crash it.

Thanks in advance,
William
