SUMMARY

The CMOS setup program on the Zenith Supersport 386sx has an option to configure extended memory for Expanded Memory Specification (EMS) services or preserve it as extended memory. EMM386.EXE and HIMEM.SYS will not recognize memory configured for EMS by the Zenith CMOS setup program. To use EMM386.EXE to provide EMS services or to use HIMEM.SYS to provide XMS services, some of the extended memory must be preserved as extended memory. If all the extended memory is configured as expanded memory, neither HIMEM.SYS nor EMM386.EXE will load.
