I can't give the full report, as it exceeds the limit. But I'll give you the motherboard section. Although, not from everest as it cannot find the name.
Board: ASUSTek Computer INC. LEONITE 5.00
Serial Number: MS1C6CS27706002
Bus Clock: 200 megahertz
BIOS: Phoenix Technologies, LTD 5.08 12/08/2006

Let me know if that's the incorrect info, and I'll try to find what you NEED.Can you post what chip is in that ? ?
Asus's site goes by board;chip and then model #...
I'm guessing it's what's known as a OEM board which means Asus cranked out a ton of them and sold them to whitebox manuf. so tracking down drivers isn't as easy as usual...Ah okay. They just had to go and make things difficult -_-.

This is all the information in the little CHIPSET section. At least, I think so.

Chipset Vendor: Intel Corporation
Chipset Model: 945G Processor to I/O Controller
South Bridge: 82801GH (ICH7DH) LPC Interface Controller
SMBUS: Intel Corporation 82801GH (ICH7 Family) SMBus controller @0500h

I hope that is what you needed, I just copied the part that was sectioned off involving the chipset. Sorry if it's not what you needed. Just tell me what it is and I'll find it.

EDIT: Don't worry about this anymore, we solved our problem through a different manner and we don't need to downgrade anymore. I really appreciate all your help though!
