WOW!! The pin 13 tape thing worked! I tried four or five different Toshiba Value added packs for my Toshiba 1905-301 and nothing helped. I even went so far as dissemble the whole machine to check the toggle switch on the side of the computer. All seemed to be good except nothing worked! There was never an "allowed" FN-F8 toggle and even now the light does not light up on the front of the machine indicating that wireless is on... but it is on now! I have a feeling that the tape works becuase it shields the input of a voltage to the pin 13. The chipset on the wireless card does not see a "deny" voltage (becuase of the tape) so it goes to an on state. it works very similar to the old copy protection on the cartiridges for the Color Computer by Radio Shack (LOL).. When the on board chipset saw a voltage applied to one of the pins, it would secure the high memory as non-writable and fill it with the chip in the cartridge. When it was denied this voltage, it would fill it in volatile memory and therefore allow someone to copy the area out to a file.
(mind you that was the copy protection from 25 years ago and tape defeated it...)
