Hi Henry... and Welcome to the AMD Forum!
Processors, like your Duron Spitfire 900 do not
have a BIOS
But motherboards, (the big PCB board that it's attached to) do
have a BIOS.
You will first need to identify your motherboard (mobo), Make, and Model (or 'version'
Then, we can help you to track down the proper version of BIOS for your mobo, and you 'flash' a new BIOS to your board.
The actual 'Release Date' of your current BIOS will appear at the top left of your very first P.O.S.T. screen. (P.O.S.T. = Power-On Self-Test)
You can hit the 'Pause' button on your keyboard to halt the boot sequence, and then any key to continue booting.
While it's on 'pause', write down the 'BIOS identifier string' that appears along the bottom of that first POST screen.
That 'string' will help us to identify your mobo.
But that's only necessary IF
your current BIOS does not have 'USB Support' already in it.
It probably does, and you simply need to go into your CMOS, (hit 'Del', the moment you hear that first 'beep' on booting up), and change it from 'Disable' to 'Enable'
