So far, I have managed to work out how to boot the computer with the Floppy in the drive. Unplug Battery, Hold down Fn+F, add Power cord and turn on, when power light comes, release FN+F and press again quickly. The USB Floppy starts to 'seek' which contains PHLASH16.EXE, MINIDOS.SYS and my BIOS.WPH, the light comes on, seems to start, then the speaker starts what I can only be described as a vibrating dull buzz and stays like it. Can anyone explain why this is happening? When I turn the Laptop on by itself, it gets to the Toshiba/Phoenix Splash screen and stops at about 20%. Any clues where I could be going wrong. I really need to get this thing back up and running.
