    Hello guys, having very hard time to recover bios after failed update. Using 1gb usb stick, file psap150.fd renamed to BIOS.fd. Removed hdd,dvdrom. Used all 3 usb inputs and all commands I know, like
    Fn+F, Fn+B, Win+F, Win+B, Ctrl+Home, Ctrl+Esc, Fn + Esc. Anybody have an idea what am I doing wrong? Thanks

    perhaps its the usb booting, try with a floppy drive if you have one and try with the battery disconnected and in the other usb ports as some Toshiba only have the rear ports available for pre boot options.

    you can pick up a USB external floppy off Amazon very cheap. It might be a good investment.

    this is from the service manual;

    Rewriting the BIOS
    1. Set the system to boot mode.
    2. Turn off the power to the computer.
    3. Remove the external cable and PC card.
    4. Connect an external FDD and insert the BIOS/EC/KBC rewriting disk into either the
    external FDD.
    5. Turn on the power while holding down the [`~] key (on the left of the space key).
    (Keep holding down the key until a message appears on the screen.) The BIOS
    rewriting starts.
    6. When the process is completed, eject the BIOS/EC/KBC rewriting disk and the
    system is automatically reset.

    obviously the [`~] is from there language keyboard so I think its just the fn alt or win key
