I recently tried upgrading a couple of X7DB8 motherboards in my lab from BIOS 1.0bv to the latest on your website. I first tried 7DB8C208.rom, but had issues with my video display, so then attempted DB8V1197.rom. I am now getting a warning stating quad-core 5300 CPUs are not supported, but didn’t get this message with the previous BIOS.
Please provide the motherboard serial number and we check to see if the motherboard released before 6/2006 or after 6/2006. If the motherboard released before 6/2006 then it not support Quad Core processor. But if the motherboard released after 6/2006 then it can support with Quad core processor but need to update to latest BIOS version.
