Upstream Linux's main ACPI cutoff, CONFIG_ACPI_BLACKLIST_YEAR has been disabled by default since Linux-2.6.9. So if a platform claims to support ACPI, upstream Linux has run in ACPI mode on it for many years. The idea was that we'd harvest and debug ACPI failures using the upstream kernels, while the distros could play it safe and set the cutoff to 1999 or even later. But a funny thing happened a few years ago. The distros stopped setting this cutoff, and nobody complained. Of course, it could simply be that few people are using machines that old anymore... In any case, I expect that versions of Windows around 1999 or 2000 had to check, but that like Linux, they don't really need to anymore. cheers, Len Brown, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
