Where is the knight [MOTHERBOARD]

Hello everyone =)

I would like to know where the jumper on my motherboard is located for removing the BIOS password?
My PC is disassembled, and I've been searching, but I can't find a jumper with the inscriptions CLR BIOS or CLEAR BIOS, or CLR CMOS, or CLEAR CMOS, or RESET BIOS or even RESET CMOS.

I have an Acer motherboard, the model is MRS600M
Chipset: ATI Express 1250 (RS600)
Southbridge: ATI SB600
LPCIO: ITE IT8718

For the BIOS...
Brand: Phoenix Technologies, LTD
Version: R01-A3
Date: 27/06/2007

So I'm looking for someone who can tell me where this famous jumper is located or provide me with a photo. =)

I hope I have been clear enough, and if you need more information about anything, no worries.
I can also provide my MSN address if someone wants to explain it to me directly =D.

THANK YOU IN ADVANCE!
Configuration: Windows XP Internet Explorer 7.0

Remove the battery; this will reset the motherboard to "zero". This jumper is sometimes located near the battery; you just need to remove it, or it may be connected to two out of three pins. For example, if it connects pin 1 and 2, remove it and place it on pins 2 and 3, then put it back in its original position.

Thank you, I found the jumper and moved the small green square from pin 2 to pin 3 for 10 seconds, then I returned it to its original position.
But now when I turn on the computer, it makes 2 quick BEEPS in a row and then another BEEP.
It says a lot of info on my motherboard and this message at the bottom: "CMOS checksum error - Defaults loaded 3

Then at the bottom it says: "Press F1 to continue, Press DEL to enter SETUP "

At the very bottom, I have "06/27/2007-RS600-SB600-6A66M49C-00 "

I'm really stuck here, and when I press DEL (delete) or F1, nothing happens.

Please help me.

Thank you in advance!

You unplug the power supply, you remove the battery, you plug it back in, turn on your computer (without the battery, of course), you turn it off immediately, you unplug it again, put the battery back in and restart normally, no more password, it resets everything....
Some will tell you to hold the power button for 30 seconds, it goes back to exactly the same thing ;)
