This convinced me to pass on this one.
The hazards of BIOS flashing As described earlier, the BIOS is a crucial component of your computer since it is always the first program that runs when you turn the machine on. If the BIOS does not run, the machine cannot boot. Therefore it is very important that a BIOS upgrade is performed properly. If it fails, it can permanently ruin the BIOS, resulting in your computer becoming a door stop. Common reasons for BIOS flashes gone bad are power failure during the flashing process, and flashing the BIOS with an incorrect BIOS version.
This is the part you want to read carefully. 
Because of these dangers you do not flash a BIOS just for ****s and giggles, but only if there is a very good reason.
