I'd like to communicate with an Embedded Controller device in a Notebook through I/O ports 62/66. When running on XP, the communication might collide with "Microsoft ACPI-Compliant Embedded Controller" driver which does the same thing. Therefore, I’d like to know whether (and how) I can communicate with I/O ports 62/66 using this driver. In addition, any informative link about what this driver is doing and how, will be highly appreciated.
