As some have said already, do not flash when not needed. I have once flashed using the flash program of my motherBoards manufacturer and it failed making my mobo unusable.
Later i learned that flashing is best done out of windows and even in dos mode.
Just now i received an old computer i'm turning into a linux server and it flashed ok but i had booted using a startup disk.
Sometimes, for older machines an updated bios can do import stuff: the old pc (333Mhz) can now use very big harddrives and faster processors than pre-flashing it's bios.
