Losing the CMOS jumper will effect your BIOS reset. I do not know how ASUS designs their CMOS, but the lack of the jumper will either continually reset the BIOS settings or maintain a stable CMOS, where you cannot reset the BIOS without properly jumpering the CMOS pins (your mobo may also have a button to reset CMOS).

You should either find the lost jumper, cannibalize another PCB for a jumper or go to a store and get another jumper to avoid instability.

The problem is that different manufacturers have different setups for the CMOS jumper, and the lack of a jumper may produce instability. I cannot predict the design of the ASUS mobo so I cannot give you a definitive answer.
