You can get the pinout from mesaflash with the --readhmid option I'm pretty sure this works with the latest mesaflash if the in kernel SPI driver works (always a question...). > Perhaps you can tell me which of the 3 kernel *-spi.ko files will turn > the parport on an x86 mobo into an spi port?

I dont think there are any parallel port kernel SPI drivers so you need to flash SPI configs with a system with a working kernel SPI driver/SPI hardware (which is why I suggest leaving one config as EPP) Peter Wallace Mesa Electronics ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
