i had the same problem as u its quite compicated but when u boot off the floppy and type in NVflash.exe etc u have to put somethin like -5 and -6 in there so it looks like NVflash.exe bios -5 -6 because that tells it to overide whatever is stopping it, read the thing that came with it, it has all the commands in there but those were the ones i used, its quite complicated but in the end its worth it
