Sony Vaio Z115GW Laptop Bios Mod Request
Dear Bios Gurus,

I have a Sony Vaio Z115GW laptop with bios details below (screenshot also attached)
.jpg   Vaio Z115GW Bios.JPG (Size: 115.43 KB / Downloads: 15)

InsydeH2O ver. 3.5
Bios Version: R3031C3
EC Version: K2020C3
ME Version:
CPU: Intel Core i5 M540 @ 2.53GHz
Memory: 8GB
OS: Windows 7 Pro 64-bit

I would like to turn it into a Hackintosh but it's said that I need to turn on AHCI mode in its bios first.
However there's no such setting for me to change even if I've already changed registry key "msahci" from 1 to 0 in Windows 7.
So I guess I need to flash a modified bios in order to install Mac OS on it.

Could someone help modify it?
Bios download link:
Sony Taiwan Official Site (in Chinese):

In case you can't read Chinese, I also uploaded it to my Dropbox.
Here is the link:

Thanks in advance.
If it works for me at the end. I'm willing to buy you a coffee via PayPal.
