Right, I've had a chance to have a good look at the motherboard. It is indeed a PC-Chips motherboard, and in large writing at the middle of the board is
M848A
Rev 2.1
And on one of the chips (looks like quite a major one) it says
SiS
963Lua
PNA4117
0331FA
I also installed System Information for Windows. It has the following ino about my board:
Manufacturer ECS
Model M848A
Version 1.0
North Bridge SiS746FX Revision 10
South Bridge SiS LPC Bridge Revision 10
CPU AMD Athlon(tm) XP 2800+
CPU Socket Socket A (462)
Thanks.
P.S. souseran, it is not a HD card. Cheers.
