Support for Acer Aspire 5100 Series
by Stefan Florin Neagu July 26, 2008

July 26, 2008

I'm pretty good with the command line, but my PC's out of warranty and debugging the BIOS is a little over my head. Wanted to ask if Open BIOS will work on Acer Aspire 5100 which is using a custom award bios that is very crippled, very few settings. Thanks!
