The interface will be in the data sheet for the flash part.  The only
thing that may be MB specific is how to assert the write enable line
on the flash.  It may be hooked up to a GPIO or perhaps some sort of

Do you have the factory flash app?  If so then you can probally run it
under dosemu and figure out what register they tweak to enable flash
writes.  Also Disable the shadow of the BIOS range and do a write to
that range and see what the write line on the flash does.  It might
just be hooked up without anything fancy.

That should be pretty easily to fix.  Most flash chips are very
similar in the programming sequence.  Get the data sheet for your part
and fixup the flash code.
