──────────────────────────────────────────────────────────────────────────── CHKSTATE.SYS Used by the MemMaker memory-optimization program to track the optimization process. During optimization, MemMaker adds the CHKSTATE.SYS command line to the beginning of your CONFIG.SYS file. When the optimization process is complete, MemMaker removes the CHKSTATE.SYS command line. CHKSTATE.SYS is used exclusively by MemMaker. ♦
