Here is the site for upgrading the BIOS on it http://support.asus.com/technicaldocuments/technicaldocuments.aspx?SLanguage=en-us AFUDOS (First Link) I don't fully understand what the site says. The reasons I need to upgrade is to support the CPU it doesn't support with factory installed BIOS. I would really like someone would fully explain this. Thank you very much !!!!
