Well in your case I started with the bios string 61-0304-000747-00101111-071595-M747
I went to
www.google.com and searched for M747 and the first hit point to good old PC Chips as I suspected. You will find that PC Chips makes boards for damm near everyone. You will also find that their service sucks as do most of their boards (my opinion).
As for the language problem... if it asks to download just cancel. Many sites have a a US flag or English that you can click on and again some times you just guess!
