According to http://bios.techpowerup.com/vgabios...er=&model=HD+3850+AGP&interface=AGP&memSize=0 it seems that all BIOS for 3850 AGP are the same. (Look at details, appears to be same BIOS revision codes). If you have such a card, could you please check your BIOS. If it is different, please post here. Thanks!
