that is worth reading. I think it will help explain why strange things happen when Linux is installed on some hardware. |

Link to the PDF: ftp://ftp.suse.com/pub/people/trenn/
ACPI_BIOS_on_Linux_guide/acpi_guideline_for_vendors.pdf Reading through that, it occurs to me how really badly designed that ACPI in the BIOS (and the BIOS in general) really is. It's so bad that http://boycottnovell.com/2008/07/25/foxconn-bios-acpi/ doesn't seem too far fetched anymore. Checking version strings is really a big no-no. BIOS designers should be checking for capabilities and not worry about what OS is running. E.g.: If ( _Have ("MonitorSuspend", "1.0") ) { # Do something clever } If ( _Have("HDDSuspend", "2.0") ) { # Do something smart } Else { If ( _Have("HDDSuspend", "1.0") ) { # Do something a bit less smart } } etcetera. This is really API design 101. Bad ACPI designers. No twinkie for you! |

Sander, your ftp link broke formating. |

Should be fixed now. |
