1- Go to and find your product. The BIOS can be downloaded as an exe file, such as sp40578.exe.

2- Install the package 'cabextract'

3- Type 'cabextract <filename> --filter ISO/rom.iso' and you'll get a directory 'ISO' with a file rom.iso

4- Burn the iso to a CD.

5- Reboot the pc from this CD and follow instructions.
