The Toshiba Linux Utilities
Toshiba are very secrative about the technical documentation for their
laptops. To help the wider Open Source movement it is my intention as I get time
to document what I have worked out about how to control the Toshiba specific
features of their laptops.
The way the features of the laptop are controlled is through two interfaces,
known as the System Configuration Interface and the Hardware Configuration
Interface. These two interfaces are implemented by using the System Management
Mode of the processor. This is present on all Intel Pentium and later
processors and all the SL seriers processors designed for laptops such as the
My current documentation on the System Configuration Interface and the
Hardware Configuration Interface can be downloaded from here as Adobe Acrobat
files. Further information can be gathered by studying the source code for the
Toshiba Linux Utilites
All Toshiba laptops have a unique identification number. Documentation on
how to read this number along with information on turning the fan on/off on
older models and detecting when the Fn key is pressed can be viewed here.
