The information in this article applies to:


 * Microsoft Windows versions 3.0, 3.0a

SUMMARY
To run Microsoft Windows version 3.0 386 enhanced mode properly on the Everex Step 386/25 machine, you need to add the following entries to the [386Enh] section of the SYSTEM.INI file:

  8042ReadCmd=A2,1,F 8042ReadCmd=A3,1,F 8042WriteCmd=B3,8,F

MORE INFORMATION
These entries are needed so that the LED front panel display works properly. These computers have a blinking lights display which usually displays information about which cylinder on the hard disk is being accessed. The display is driven by a set of non-standard commands to the 8042 keyboard controller. Normally the Enhanced mode VKD (Virtual Keyboard Device) just ignores non-standard commands such as the ones that drive this display. The result is that when you start Enhanced mode the display suddenly stops working and ceases to indicate hard disk cylinder access. These SYSTEM.INI entires cause the display to start working again.
