PC detects wrong CPU despite correct jumper settings!!!

[bluejay_fr]

I need help,

I'm building up a new computer from old parts.

My old motherboard (ASUS P2L97-C) is used to a PII 266 Mhz MMX and I've just upgraded it to a PII 300 Mhz. It's an old motherboard so it doesn't detect CPU type automatically. After setting the jumpers, I got the BIOS to recognize the 300 Mhz bit but it still detects MMX when there isn't, as if it were nostalgic of my old processor...

How can the motherboard to detect the correct CPU type? Are there jumpers I have to change to get rid of MMX configuration?

Thanks a lot if u've got an idea

If the BIOS recognizes the correct speed for the CPU, then there's no need to be concerned about the MMX.
In fact, if all of the parts are old, and everything is getting recognized and the system is working ok, then that's a very good thing.

Ever since the release of the MMX instruction set in 1997, all Intel CPU's and most AMD CPU's have MMX. This includes all PII's so this is not an error.
