Upgrade configuration?

I am about to install two 4GB memory modules into my Dell Studio 1558 (to replace two 2GB ones). I got them from Crucial (strong recommendation, by the way) and the little instruction leaflet tells me that I might be prompted to update my computer's configuration when I re-boot. What exactly will that entail if I have to do it? I didn't need to when I've updated older laptops, so how common is it?

Uncommon, applies probably more to servers etc. It's just a standard leaflet they put in.

i.e., when you next boot up the system the BIOS might stop and display a warning that it has detected a memory configuration change, press F1 to continue..

But is it easy to do if it does happen?

Yeah, it's self-explanatory

The hardest part was getting the cover off the memory modules underneath the laptop. Resisted the temptation to stick a screwdriver in there and prise it off! Thanks for the help.

Going to update your sig then

Oooops! Watch this space.

How's that?
