viakey

DOS tool for probing VIA VT82C42N keyboard controllers.

Usage

Run VIAKEY.COM. If a VT82C42N keyboard controller is found (either standalone or integrated to a VIA southbridge), its revision code will be displayed. Any errors in the probing process will be displayed on screen.

The amikey tool can perform a more detailed probe, as the VT82C42N is compatible with the American Megatrends AMIKEY.

Building

• Windows: Run build.bat VIAKEY with NewBasic present in %PATH%.
• Other platforms: This tool is only guaranteed to assemble and function properly with the (DOS- and Windows-only) NewBasic assembler, but feel free to try other assemblers.
