There is a fair number of board and chipset-specific config that should be modifiable without recompilation but are probably inappropriate for CMOS for various reasons as CMOS size shortage or the need for persistance even across RTC power well failure [aka bad clock battery] (think MAC address). having fixed indexes doesn't scale. > Patches accepted :-) > > > Patrick > > >
