[REQUEST] ASUS P5K3L-ASUS-S1-P5G35/Essentio CS5111 Increase Max RAM

[ewastesupreme]

Hello. I have an ASUS Essentio CS5111. It currently has the last supported BIOS (1403) installed. There is one additional, final BIOS version (0101), which the ASUS website says: 
'*Only support native Win7 system with Win7 Recovery DVD*Do not update this Bios version if your system are not native Win7 system.'
I am not sure which OS this machine had on it before I got my hands on it. I doubt it was the Windows 7 version. I am unsure of what issues it would cause to put the 0101 BIOS on the machine.
 The SUS P5K3L-ASUS-S1-P5G35/Essentio CS5111 only supports a maximum of 4 GB of RAM (2x2 GB). I have tried using more than 2x2 GB and the machine will not post. I am hoping the max RAM could be increased to 8 GB (2x4 GB) in a modified BIOS.
I think the best BIOS to modify would be 1403 as I am unsure of the viability of 0101. The machine is a dinosaur I am hoping to bring back to life with Linux. 8 GB of RAM would make it a much more practical machine. I appreciate any assistance that could be offered. I hope this is the right forum to post this.

At first try to find any motherboard based on G35 chipset with support of 4GB DIMMs.

It is one of these little tiny things. No mobo switch possible.

Any(!) motherboard with necessary support to check its BIOS.
I think it doesn't exist.

I understand now. What I am asking is essentially impossible. 8 GB is only possible with 4x2GB due to the G35 chipset. Thank You for responding.
