> Does booting with acpi_osi=Linux makes things any worse? acpi_osi=Linux will make Linux answer YES if/when a BIOS asks OSI(Linux). However, it does not change if/when the BIOS asks if we are XP, nor would it change our (YES) answer if asked. Unlike all previous uses of OSI where what matters is what Linux ANSWERs, this port blocking feature depends on what the BIOS ASKS.
