RE: ACPI OSI disaster on latest HP laptops - critical temperature shutdown

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The goal for ACPICA has gone from being a complete "reference
implementation" of the ACPI specification to being a "Windows
bug-for-bug compatible" ACPI implementation.

So when we report _OS("Microsoft Windows NT") and respond OK to all _OSI
queries with Microsoft strings, we mean it.
