This one W O R K S ! ! !

This is the first driver I found on the net that actually works on the 82C931 board. Everything I tried or locked up the puter, or missed some files. This one is installed on 2 different puters using Windows 98 first edition, and seems to have no problems.

The procedure to install was

1 - Copied the MED3931 dir to HD (it didn't wanted to install from CD-ROM)

2 - removed all OPTI16 references from the system menu

3 - Used SETUP from \med3931 dir to install applications or what eles it installs

4 - restarted the puter

5 - when PnP (Plug and Pray) detected the board, used the drivers on \med3931

6 - It works! eeehhh!

Greetz everyone from Brazil!
