|
* lots of information from the Linux "specialix" driver by Roger Wolff
|
|
* <R.E.Wolff@BitWizard.nl> and from the Intel CD1865 "Intelligent Eight-
|
|
* Channel Communications Controller" datasheet. Roger was also nice
|
|
* enough to answer numerous questions about stuff specific to the I/O8+
|
|
* not covered by the CD1865 datasheet.
