The parallel port diagnostic performs the following:
1. sio_passive_lb – Sets up the SuperIO configuration register to enable
extended/compatible parallel port select, then does a write 0, walk one,
write 0 x ff to the data register. It verifies the results by reading the status register.
2. dma_read – Enables ECP mode and ECP DMA configuration, and FIFO test
mode. Transfers 16 bytes of data from memory to the parallel port device and
then verifies the data is in FIFO device.
