The two unknowable issues with IBM:
- enable SPD
- enable FLASH write
I thought the openbios/devbios code that i posted and made reference to had the corresponding addresses for enabling flash write for the i440bx chipset? (or is this another issue? ...i thought it was really an mtd issue.)
devbios generally knows how to do this for certain chipsets, including the 440. Unfortunately some mainboard vendors additionaly protect flash write with some undocumented GPIO circuit, so supporting the chipset alone is not enough. There is not much you can do except gnireenigne esrever existing firmware or trying out all possible GPIO lines (and combine them etc) The first is probably illegal in some countries, the second might destroy your hardware, esp. on laptops.
