I just installed a core 2 duo in my machine, and when it boots up, it says, "to get the most power, update the BIOS!" Well, i know that. I just haven't done it yet.
TL;DR - Look at picture, is the processor running at maximum capacity? (listed as 3.0 Ghz, currently running at 2.4)
I am running into two problems:
1) After some research, it's looking more and more like the only way to do this is via a 1.44" floppy drive. I have the right file (i think...see next problem), but all indications are the the only way to move it there is the floppy. I don't have a 1.44" drive. Is there another well known option that i'm missing? That brings me to problem 2:
2) Turns out, that even though my MOBO is a p5gc-mx 1333, it's not actually an ASUS bios set. Its an "American Megatrends" Bios. Maybe a knock-off board? I have the Asus BIOS file, but the setup lists the BIOS file as AMIBIOS, rather than P5GCMX.rom (as per Asus' instructions).
So i have attached the picture below, to simple ask: Is the chip running at maximum efficiency? Bios says its 3.0 Ghz, also saying there are 2 processors, currently running at 2400Mhz. Is it clocking that speed because nothing's happening? or is it stunted at 2.4Ghz, but 2 cores, i assume?

Sorry for all my confusion, but I'm extra confused because i haven't seen a huge speed increase in the windows environment in any way.
Attached are two pictures.
