Toshiba Satellite P25-S520 - USB Boot

[JoseyWales]

I'm looking to see if there is a BIOS upgrade available for my Toshiba Satellite P25-S520 that would enable me to perform USB boots. I suspect that it's impossible but I'm holding out hope that some Linux aficionado has figured it out [my dream is to boot to Linux using my Seagate USB 2.0 Pocket Hard Drive hard drive!!!]

Thanks

the bios made by phoenix will not let you usb boot anything. I have a very similar model with same bios. Sorry.
