But i can't find any correlation between the BIOS %eax parameter and the SMI commands. Shoudln't they share the same entry point ? In my case, i can control multiple thermal zone + fan using bios, but not using ACPI. I hope my question is clear enough :) bye --- nicolas ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
