The dreaded TOS1901 missing device on Toshiba Laptops (Fixed)


Since Windows Vista 64-Bit was introduced, many Toshiba laptop owners have been left with a single Unknown Device in Device Manager. This device is the Firmware Linkage Driver. While this device does not appear to affect system performance; it is annoying to have one Unknown Device in your Control Panel. The Firmware Linkage Driver  has the Hardware ID’s of TOS1901, *TOS1901 and ACPI/TOS1901.



Eventually, it was discovered that this particular device was installed as a part of the Toshiba Supervisor Password Utility. This SHOULD have resulted in a simple fix but Toshiba made this utility locked to a specific set of Serial Numbers.* This meant that if your laptop had a serial number that wasn’t in this set, you were out of luck. The program would refuse to install and the driver would not load. I tried to get an image of this, but not that I have the Firmware Linkage Driver installed, I can't seem to get it to bring up an error.

For several years now, I would randomly try and find that driver. Well, this evening I successfully found and updated it. The process was so  simple I have been kicking myself. The installer is browseable, if you use the right programs. So long story short, I was able to extract the Firmware Linkage Driver from the install file. See the image below, showing the driver installed on my Toshiba M115 running Windows 7 64-bit Professional.






Now here are the drivers for you:
Download Driver  - XP (unknown if only 32 bit or if XP64 works as well), Vista (32 and 64 bit), Server 2003 (unknown if only 32 bit or if 64bit works as well), Win7 (32 and 64 bit).

Please let me know if this helped you out. Also, please report other operating systems that these drivers DO install on (ie Server 2008, Server 2008 R2, XP64, Server 2003 64 bit, etc.)
