I need the BIOS file A12 for a Dell Dimension XPS R450 if anybody can point me to the right direction. I upgraded to the BIOS A13 which is unfortunately blocking me from using my Pentium 3 processor in the computer.
i googled and got this - http://www.roberthancock.com/dell/xpsrproc.htm which in turn led here - http://duhvoodooman.com/ - half way down the middle of the page - http://duhvoodooman.com/xpsrbios/xpsr_a12.zip
