Sony Vaio need BIOS mod for 4GB Memory

[khoanb1]

Hello Everyone,

Thank you for seeing my thread. I´m newbie in this forum and now I have a very important problem with my Bios, I need your help!

I have recently upgrade my Sony Laptop VGN-N130G to run some virtual machines on it, but the BIOS does not support Virtualization Technology and AHCI feature. After some researches, I have already actived those two feature with SymCMOS utility.

But when I upgrade the memory up to 4GB (2 slots, each slot have 2GB memory), the BIOS and Windows 7 64bit recognise only 3GB. I looked for mapping or remapping feature in STRINGS0.ROM but I did not see them.

So, I post this BIOS in this forum for help. Any modifications or guides are very aprreciated!

Thank you!
