Introduction
The purpose of this article is to provide information on how to update the BIOS of a PC.
Computer vendor independent updating methods
Windows 7 System Repair - http://askubuntu.com/a/237742

HP
Go to http://welcome.hp.com/country/us/en/support.html and find your product. The BIOS can be downloaded as an exe file, such as sp40578.exe.
- Install the package 'cabextract'
Type 'cabextract <filename> --filter ISO/rom.iso' and you'll get a directory 'ISO' with a file rom.iso
- Burn the iso to a CD.
- Reboot the pc from this CD and follow instructions. Backing up the BIOS did not work for me.
These instructions worked on a laptop, but it might be different for some other models. Then just cabextract all files to find your iso to burn.
