Part of the 32-bit address space is reserved for various I/O-devices. This means that a 32-bit OS will not be able to use all 4 GB of RAM but only a smaller amount (usually around 3.5 GB.) If you were to use a 64-bit OS it would probably be able to access all of the RAM if some of it is remapped to above the 4 GB line. (There is usually an option in the BIOS to do this remapping.) (This information is provided by most motherboard manufacturers and many computer manufacturers (including Dell) in some FAQ. ) -- <Insert your favourite quote here.> Erik Trulsson [EMAIL PROTECTED] _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
