    Hi people.

    I've tried to read the BIOS from my card for some time now, but always failed. Tools always claim that the BIOS is locked or simply dump files with 64kB of the same values over and over.
    I have a Cebop TOP700 latop based on the Uniwill 259IA3 barebone with a M11 Radeon 9700 Mobility (0x4E50) and 256MB of RAM.

    I dumped some information with ATItool:
    Code:
    Display adapter               ATI MOBILITY RADEON 9700 AGP (0x4E50)
