Updating the bios of a PC or Laptop is most times targeted at that other operating system. Here are some answers.

Dell

• Install the package firmware-addon-dell
• See also [1]

HP

• Go to [2] and find your HP-product. The bios can be downloaded as an exe-file with a cryptic filename, 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-RW (or CD-R if you are a big spender)
• 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.
