Although each machine is differnet most require that you tap the delete button at boot up to enter the BIOS setup. Yours may or maynot be different. Watch your screen closely and it will tell you what key you have to hit to enter "advanced setup or advanced settings". Here is an excellent site to find out what the settings are and what they do, as well as how they should be configured. http://www.rojakpot.com/default.aspx?location=7&var1=18
