No - RAM has nothing to do with the split. Process memory is the amount of virtual space allocated to the user; the OS may choose to use much less RAM behind that virtual space. Page thrashing may occur, but the process still gets to play with what it thinks is 2GB of "memory". > This is because there needs to be some way for your process > to interact with the hardware and kernel. The global and local descriptor tables and the page directories/tables provide the translation between virtual space and RAM. There need not be any split between user space and kernel space, but it's useually more efficient to create such a boundary. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
