    This is the first universal bios editor for Radeon-based videocards. This program let you modify clock speeds and BIOS fonts for any videocard based on R100, RV100, RV200, R200 chips. Version 0.95 - was the first public release. Program accepts bios image file as input data and generates correct output bios image file as a result of processing. Program has variations as described below (you can download this progs from here):

 • RadEdit.exe - Windows version of editor with GUI

 • RadClk.exe - Console Windows version of editor

 • RadClkD.exe - DOS version of editor

    Comprehensive user guide will be available soon. Below we've published some hints for using these programs.

Windows GUI version

    Main screen:

    BIOS editing procedure:

 • load bios image into editor (from file in *.rom format);

 • change clock setting as u like (this settings will be default for your videocard). Note: For videocards based on chips R100, RV100 clocks should be synchronous.

 • load another fonts with alternative language symbols for example, (this procedure will be described later);

 • press button "Update CRC" for updating CRC and checksum;

 • save resulting bios image into file.

    Command-line parameters description:

    RadClk [/d] [/l|/s] bios.rom [core_clock memory_clock] [newbios.rom]

 • RadClk - program name;

 • /d - display chip initialization parameters

 • /l - load fonts from files font8x8.fnt and font8x16.fnt into bios image file;

 • /s - saves fonts from bios image file into files font8x8.fnt and font8x16.fnt;

 • bios.rom - input bios image file name;

 • core_clock - in MHz;

 • memory_clock - in MHz;
