MORE INFORMATION

4. NOTES ON WINDOWS

4.1 Windows/286 2.1

If you run Windows/286 2.1 with MS-DOS 5.0, use PIF Editor to specify a value of 128 in the KB Required option for COMMAND.COM. For information about using PIF Editor and PIF options, see the Microsoft Windows User's Guide.

4.2 "High Memory Area in Use" Message (Windows/386 2.1)

You cannot run Windows/386 2.1 when MS-DOS 5.0 is loaded into the high memory area. Also, the MS-DOS 5.0 versions of SMARTDRV.SYS and RAMDRIVE.SYS are not compatible with Windows/386 2.1. To run Windows/386 2.1 with MS-DOS 5.0, use the versions of SMARTDRV.SYS and RAMDRIVE.SYS that came with Windows and remove the DOS=HIGH command, if any, from your CONFIG.SYS file.

4.3 "Cannot run Windows in standard mode" Message

If you have a DEVICE=EMM386.EXE command that includes the RAM or NOEMS switch in your CONFIG.SYS file, you cannot run Windows 3.0 in standard mode. Either remove the RAM or NOEMS switch or run Windows in real or enhanced mode. (If you remove RAM or NOEMS, you won't be able to load programs and device drivers into the upper memory area. If you include RAM or NOEMS, you won't be able to run Windows in standard mode.)

NOTE: Using EMM386 may reduce the amount of extended memory available to Windows and cause Windows to try to start in standard mode. To prevent this, reduce the amount of extended memory that other device drivers use. For example, if you are using SMARTDrive, try setting the MinCacheSize parameter to 0.
