Processor speed wrong

Hello all, I'm hoping you can help me out.
My setup is:
AMD 1.1 proc
256 DDR Kingston Memory
Asus A7M Motherboard

My problem is that I did a reformat last week, and now my computer reads the processor as an 850 instead of 1.1
Anyone know of a way to correct this? Hopefully without reformatting again.
Any help would be appreciated.

You need to change the multiplier/frequency settings in the BIOS for the processor.

Go up one step at a time, until you get to where you need to be.

If all of a sudden your computer wont boot, reset the CMOS.

**NOTE EDIT**
Reformatting should have nothing to do with it, the only thing that changes is the hard drive. What's wrong is in your BIOS. However, I'm not too familiar with that low speed processor but I'm more than certain it is a BIOS problem.

Try loading up the BIOS' default settings...

If that doesn't fix it, try resetting the BIOS (should be a jumper you have to short, check your manual)...

Then it'll clear all the settings, and should detect your cpu for what it really is...

If it still won't recognize it as a 1.1, do as XtR-X said about setting the clockmultiplier and FSB manually...
