Did you load "insmod pnpbios" the first time (as opposed to built-in)?

This is "NO DMA" (we map this in parport to -1, which means Unknown).
Your PNPBIOS is buggy, this should be "08" for dma=3

Possible settings are: 08|02 i.e. dma=3|1

Try to get an update for your BIOS or file a bug report to your
mainboard vendor else.
