i don't know the guts of fedora/rh... but i would imagine that a chunk of the mem space is reserved for system operational functions. as a result, the mem space that you, the app has, is the mem that's left over for apps to play in..
the reserved mem space might be used for swap, mem checking, error checking, os kernel functions, etc... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mike Chambers Sent: Wednesday, October 01, 2008 9:33 AM To: Community assistance, encouragement,and advice for using Fedora.

Does that work on only 4Gb or more? I have 2Gb Ram, and running 64bit, and still only see 1.8Gb of memory, as it did with 32bit as well. -- Mike Chambers Fedora Project - Ambassador, Bug Zapper, Tester, User, etc..
