acpica-unix-20050902.tar.gz is now available under: http://developer.intel.com/technology/iapc/acpi/downloads.htm Thanks. There is one concern: This has been discussed some weeks ago. The compiler throws dozens of errors on some DSDTs: DSDT.dsl 777: , AddressRangeMemory, TypeStatic) Error 1084 - Missing ResourceSource string (required) ^ I cannot find the mail now, but IIRC Len said this was added to identify how many DSDTs violate specs (is it optional or not?) and should be removed again later. The patch attached lowers the error to a warning, so that you get a compiled DSDT as output. Not sure, maybe the error/warning case should be reverted totally? Thomas
