This document: http://download.microsoft.com/download/e/b/a/eba1050f-a31d-436b-9281-92c dfeae4b45/mem-mgmt.doc has a great deal of information about how Windows handles memory, both physical and virtual. It contains this paragraph: The physical address space is used to address more than just RAM. It is also used to address all of the memory and some of the registers presented by devices. Consequently, if a machine is configured with the maximum amount of physical memory, some of that memory will be unusable because some of the physical address space is mapped for other uses. > If that is within windows - there is an option to tell > windows to work with a 4Gb limit instead of the default 3GB limit I don't think so. There is a /3GB switch in boot.ini (IIRC). That governs the way virtual memory is used, it has nothing to do with physical memory. (Each process gets a 4GB virtual memory space. Normally, 2GB of that is reserved for the OS, and the program can use the remaining 2GB. If you specify the /3GB switch, the OS will have to make do with 1GB of VM, leaving 3GB for the program.) -- Tim Slattery [EMAIL PROTECTED] -- ---------------------------------------- The WIN-HOME mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
