In the address bar, after launch, type information.
Then select system information.
Write down the bios info. Use it for a search. There is nothing about the bios on the support page for the Aspire SA80; they simply list drivers for the machine. No bios identifying information is provided for me to pursue a search. But, scurrying around, I hink the bios for the motherboard is at this address and that may be as updated as it gets. http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?DetailID=523&MenuID=1&LanID=0
You will find links to the mother board manual and bios there.
I think that is a Celeron D 336 with the motherboard manufactured by Company Elitegroup Computer Systems,ECS 661GX-M7 . The device drivers are available at http://acer.driversdown.com/acer-drivers/s_195_1.shtml
