    hello all,

    I flashed the wrong BIOS on my Toshiba P300 - 11M (PSP4DE)

    the laptop displays a black screen. the laptop will light anyway since the fan is running.

    Ps: I try the technique with "crisdisk" and creates a key USB but I do not know the good séquance key (fn + b ...) to boot on USB for this model.

    could someone help me? :worthy:


    Thank

    Assuming that you know how to obtain the BIOS.WPH file:

    download this enhanced version of "Phoenix CRISIS DISK"

    extract the content, copy BIOS.WPH in the extracted folder.
    prepare a USB stick or floppy with WINCRIS.EXE
    (you may have a better result with USB floppy)

    now it seems that the difficulty is to find the good key sequence to trigger the recovery.
    (Usually WinKey+B for HP and Fn+F for Toshiba)
    can be:
    Hold down: Fn+B or Fn+R or WinKey+B or Fn+B and CTRL+HOME (all the four keys simultaneously) (On some new Acer Laptop's Fn+Esc and on some new Fujitsu Siemens Laptop's Fn+F) and while holding plug the AC adapter and press the power button.
    If one of the key sequences does not work try with the other one and so on.
    But shut down the computer before you try another key sequence.

    Now you should hear the floppy drive working, or USB stick blinking, hold the keys for a while and then let go.
    Successful flash was signified by a pause after the incessant beeping followed by another beep and the laptop shutting down.

    let me know

    The good key sequence for Thosiba is Fn+F
    And the recovery should work with a USB floppy.
