I have an Acer Aspire desktop x1420 with Windows 7. To run two monitors I added a ATI Radeon HD 5450 card. The computer still sees one monitor and the new video card. I am told I need to update the Bios. The Bios vendor is American Megatrends Inc, date 4/20 11 DMI version 2.6 Bios version P01***TRIAL***. I have not been able to beat windows start up to get to the bios set up,but when i do ... what do I want to update? I am a novice. it's taken me hours to get this far...
