Well, removing and replacing the battery and jumping the cmos essentially do the same thing, and yes, all mobos have the battery but I have never seen a mobo that was made within the past few years without a jumper...

The reason why they have a jumper is because it was easier and faster to jump the cmos rather then take out the battery wait a couple minutes then put back in.
Right, but I said that because the battery answer was one they had on the test.

The questions on the tests don't have the most current information. The network concepts "cert" are also outdated. Quite a few questions refer to windows 98 and windows nt. They have certs that are specific to xp and 2k though, they are newer questions.

I've seen recent laptops (read within the past 2 years) where there are no jumpers on the mobo, just the batery that is a pain in the arse to get to.
