No, I don't think this can be done generically - _ADR for a SATA device has a format that looks similar to the one for PCI devices, for instance. I think you need to have knowledge of the specific device type. > This has been tested on a Dell 610 only then? > This sounds like an older machine, I wonder whether the video driver is > useful on this one at all and whether Windows had to check whether the > devices are present also... Also on an HP 2510p. I suspect that the Windows behaviour is to leave this up to the graphics driver rather than handling it in the core. Toshiba seem to have implemented the complete spec for some time, but several other vendors only implemented the section for display output switching and obtaining the EDID. > Please tell me if you have tested more machines, I try to give it a test > on a Toshiba, Lenovo and whatever I find with a Vista capable BIOS (IMO > this should be the most important criterion for finding the devices, I > doubt older Windows Versions made much use of ACPI graphics devices) as > soon as I find some time... Yes, I've tested it on some other machines - the HP is the only one I've tested with a designed for Vista badge, but it should be correct in these cases as well. -- Matthew Garrett | [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
