The recent Thinkpads I've played with have all triggered interrupts on IRQ 9 when hitting the nvram hotkeys. ACPI registers this as a shared interrupt, so possibly there's some hope of being able to hook in there? I'm not sure if this is the case on all machines, so it might require a table for polling/non-polling behaviour. -- Matthew Garrett | [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
