SUMMARY

According to Dell Technical Support, Dell 486 machines have been tested (by Dell) with Microsoft Windows 3.0. If Windows does not install or run properly on a Dell 486 computer, the hardware cache and BIOS shadowing should be turned off through the CMOS setup. To access the CMOS setup, press CTRL+ALT+ENTER at the MS-DOS prompt.

MORE INFORMATION

On 486 E, TE, DE, and SE models, the CMOS settings to disable are FAST VIDEO and 486 CACHE. On 433P models, the settings to disable are FAST SYSTEM and FAST VIDEO.

Dell 486 systems shipped with MS-DOS 3.3 or 4.01 may also include PC-KWIK software for disk caching. If PC-KWIK is being used, it should be disabled.
