A lot of the NS superIO's are very similar.  The cases I've seen so
far are just  addition/subtraction of all the "special" features. 
Like fan control, power control stuff, special purpose gpio.  The FDC
between the 2 may be identical.

Yeah.  It just has a 440bx chipset on it.

Good choice. The only thing better than a bios savior is a ROM
emulator but it's lots more expensive.  Make sure when you order your
replacement flash that its supported by flashrom.  Most are but check
to make sure.  You don't have to get the exact brand of flash thats in
the board since the factory part may be hard to find.  Only the size
and speed (and supply voltage of course) needs to match.

If you have any doubts about what chips will work just post up the
part number (The one _under_ the sticker) on your bios chip and we
should be able to cross it for you.
