There are several sources that say to set a the boot parameter acpi_osi in Grub .1, 2 Even though ACPI 3 was available in 2005, newer systems often support version 1 or version 2.3 ACPI 1 and 2 specified _OS as a string that shows the operating system. ACPI 3 specified OSI. Many BIOS still use _OS. It is acpi_os=Linux, not acpi_osi=Linux that resolves the high fan speed and black screen issue with AMD cards and fan speeds on legacy chip sets. This may not work in all instances.4 It seems that some BIOS configuration need _OS rather than _OSI.
