Some of your RAM is being used by your system for video, BIOS "shadowing", reserved memory, etc...It;s motherboard, chipset and BIOS dependent...

"azasadny" is correct. The system is using that 'missing' memory for the onboard graphics chip and possibly other things like caching the BIOS into memory.

Look at the docs regarding BIOS options, every motherboard has some common options and some have very specific options that will give you better performance or lower power usage (laptops). Only make one change at a time...Good luck!
