For interrupt-driven mode: irq=auto dma=nofifo For PIO mode: irq=auto dma=none For DMA mode: irq=auto dma=auto
You need to check the 'dmesg' output after parport_pc has loaded to see exactly what it will use though (i.e. whether it has detected usable hardware).
The line that goes 'parport0: PC-style at 0x378 (0x778)' is the important one. Ignore the stuff in [brackets] at the end; if an interrupt is mentioned it is using it; if a DMA channel is mentioned, it is using it; and if it says 'using FIFO' then it's using the FIFO with programmed IO (rather than DMA).
