Abstract
In a memory management method for a computer with a hard disk drive, the hard disk drive is first partitioned into at least one system disk drive for storing system files therein, a data disk drive, a system buffer space and a read/write table. Thereafter, the computer is selectively operated in one of an unrestricted mode, where storing of the system files and modifying of the system files in the system disk drive by the computer are permitted, and a restricted mode, where modified portions of the system files in the system disk drive are stored by the computer in the system buffer space instead of the system disk drive to maintain the system files in the system disk drive in their initial form and where the read/write table is updated by the computer to record addresses of the modified portions in the system buffer space and addresses of portions of the system files in the system disk drive corresponding to the modified portions therein.
