ASUS P4 S333 mobo will not boot

Client has a homebuild pc with an ASUS P4 S333 m/b. He reports that he entered the bios and changed the CPU speed from "22662 to "manual". Now the pc will not boot.
Do I have to clear CMOS to get in again, or is there a jumper setting somewhere that will enable me to boot the machine and get back in to put the settings right?

Sorry, that should be "2266".

Thanks.

Thanks guys, but I know how to clear CMOS . What I'm wondering is whether there is a jumper setting on the board which will let me back in, now that CPU speed is set to "manual".
That setting will be lost when the CMOS is reset.  The BIOS will revert back to fail-safe (factory) settings.

garycase,
             thanks for the suggestions. I already looked at the manual, and it appears that the client changing the BIOS setting to "manual" should not affect the pc's ability to boot. I finally got the thing to POST after 4 or 5 cold boots: single beep and then straight into the BIOS screen with this message:

"during the last boot-up, your system hung due to improper frequency combination..."

I have Googled this, and it seems that a lot of Asus m/board owners have this problem. Fixes include all kinds of fiddling with BIOS settings; changing the graphics adapter; disabling the Q-fan in Hardware Monitor (?) and on and on. I'm going to try to work through some of these. The CPU frequency settings are all correct as far as I can see, and have not been changed over the 3-4 year life of this pc.

If anyone has any first-hand experience of this particular Asus m/board problem, please let me know.
OK, thanks everyone for the input.
This intermittent boot problem appears to be endemic to a particular batch of Asus m/boards - gooling it threw up dozens of forum posts about it.

My client has decided that rather than a new m/board, he is going to leave his pc powered on 24/7, and restart it every now and then to sort out the RAM!

Thanks again for your help.
