Asus G2P 08G27AC0021I Rev 2.1 Memory Fix

I have an Asus G2P laptop
Motherboard part # 08G27AC0021I Rev 2.1

The board is basically a revised and upgraded Asus A7C

It has the Intel PM945 chipset which allows up to 4Gb of memory.

You can put 4Gb of memory in and a Linux Kernel will see it but due to BIOS limitation in addressing only 2.4Gb is ever available.
This is a great desire in the community for an updated or modded BIOS to correct this issue but Asus will not release an update to the community.

The latest BIOS can be found: http://dlcdnet.asus.com/pub/ASUS/nb/G2P/G2Pas204.zip

2.4Gb is just not enough memory anymore. It supports a nice set of Processors scaling up to the 2.4Ghz Dual core and with the SATA II channel and a SSD plus the 512 dedicated x1700 video card it's a nice laptop and would be viable for use for another 2 years if only it supported the 4Gb of memory the chipset should allow it to support.

Please help us. Thank you.

The implementation of this laptop was done with a 32bit OS in mind which supports maximum 3.2GB or something, depending on how much the video card wants of the address space below 4GB. I have seen someone putting 1GB + 2GB sticks in this laptop for a total of 3GB, it seems to me that's the best thing you can do, it will give you a bit more room until you sell it asap and buy something with more expansion possibilities... The model was introduced in 2007, that is almost 5 years ago, time for write-off anyway...

I have a 2 and a 1 in it right now and it'll only show 2.4 usable even though Linux will show all 3. Three gig's of RAM is still considerably better than 2 or 2.4.

While I'd love to buy a new laptop, they are still quite expensive, this was 1000$ when i bought it in 2007 and a comparable one with the dedicated 512 graphics a 2.4 dual core and 2 gb of memory would still cost me a a good couple hundred dollars.

I was hoping it'd be easy to add in the support to allow the BIOS to see and allocate out the extra memory.
