Video BIOS The Matrox MGA Millennium board has a flash video BIOS that can be updated like a system BIOS, using a flash utility. This is achieved as follows: 1 Create a DOS boot diskette, and copy the following files to it: • xxxxxxxx.bin (a binary file whose name depends on the version) • dos4gw.exe • progbios.exe • updbios.bat 2 Switch off the PC, and take out the Matrox board (this is necessary since the board switches are not accessible whilst it is in place). 3 Set SW-1, on the Matrox board, to ON (BIOS unprotected). 4 Reinstall the Matrox board, insert the boot diskette, and switch on the PC. 5 Run the updbios.bat command file or progbios.exe -i *.bin. 6 Switch off the PC, and take out the boot diskette and the Matrox board. 7 Set SW-1, on the Matrox board, to OFF (BIOS protected). 8 Reinstall the Matrox board, and switch on the PC. Executing progbios.exe -d allows the BIOS revision date to be checked. The video BIOS revision number can be checked by clicking on the MGA control panel (Display Properties/MGA Settings/Advanced for Windows 95). 51
