Hello, This file bios of an toshiba. The ROM file is 2080Ko h$$p://support1.toshiba-tro.de/tedd-files2/0/bios-20100510134014.zip The chip on the laptop is an 8Mb, so I need to cut the rom file to 1024Ko. I searched for NAPI string with an hexadecimal editor, but this string isn't at the start, end or exact middle of bios... Anyone can help and explain me how to cut this file please? The first part of file to 1024Ko seem correspond to an bios, but I'm really not sure... Thx!
