    I am trying to implement the fix for Rev. G silicon where I do not remap the FMI to jump to Bank0 , and instead just jump to 0x80000 to execute the code. The problem is the interrupts do not remap, and I cannot figure out how remap them. If I set in Bank1 the irq_handler address to bank 0, the interrupts work, but then of course the interrupts do not work in bank1 (which is a problem).

    I would have thought it would have remapped itself once the new code initialized, but that is not the case. Any suggestions would be appreciated. THanks

    You have to dig into assembly :)

    Check attached files, beware of start-up codes and changes in linker files, they are CRITICAL to proper IVT forward.

    Modify according to your needs.
