[SOLVED] Can a motherboard have both a cmos button and a cmos jumper?

[Allen_22]

At least this seems to be the case for mine, according to it's pdf. If this is the case should i use both or is one enough?

If you're referring to how you reset the CMOS, you only need to do one. Or simply remove the CMOS battery for a minute.
What motherboard is it?
