    Note concerning SLIC 2.1 modification on new ACER bios.

    note to moders,

    Starting with Acer Aspire 5552G 2.13 and Acer TravelMate 5740 1.23 a new SLIC protection/activation have been put in place by ACER.

    How to recognize these bios:

    When AndyP tool pause at the end of bios dump, we can see that the tool inform of 2 empty modules.
