when you take out the battery... it results in all settings going back to default. Thats the ol' standard message. if you had just used the jumper, you likely would have gotten the exact same message. Nothing is wrong, happy trails.
CMOS battery failure- You did remove the battery, remember?
CMOS chescksum error- there is nothing stored in the CMOS now because you took the battery out, remember?
CMOS time not set- the time is now blank because once again, you took the battery out, remember?
