Acer Aspire M5-581T w/ InsydeH2O 2.11 BIOS mod request

Hello everyone!

I've been looking high and low on how to downgrade my BIOS on my Acer Aspire M5-581T and it seems like it's not possible (or at least I haven't found a reliable source!) I came across this website and it seems like this might be my only solution!

I am currently trying to setup my laptop as a hackintosh but it wants me to set a Video RAM size in the BIOS. When I look at the BIOS I don't see anything about adjusting any video RAM size.

Here are some pictures of my BIOS:







Here is the official download link to the BIOS from Acer: BIOS

I would greatly appreciate it if it's able to unlock many features so I can customize my video RAM and also enhance my over all experience

Thank you very much!

(OOPS! I just saw that I posed this in the WRONG section, stupid me I had the unlocked and the requests tabs open and I didn't see which one I posted in! Please move to the right area, Thank you very much!)
