Bios Mods -The Best BIOS Update and Modification Source

Thanks to DeathBringer, using a Cedar Mill Pentium 4 CPU is now possible in a Dell Dimension E310/3100. Bypassing Dell's "incompatible processor detected" warning ended up being the solution. The mod is attached, just extract the .exe and run it like you would Dell's stock BIOS.

I've upgraded to a Pentium 4 HT 651 SL9KE and it's working like a charm, extremely quietly too.
