help
This option causes the pdc202xx driver to enable UDMA modes on the
PDC202xx even when the PDC202xx BIOS has not done so.
It was originally designed for the PDC20246/Ultra33, whose BIOS will
only setup UDMA on the first two PDC20246 cards. It has also been
used successfully on a PDC20265/Ultra100, allowing use of UDMA modes
when the PDC20265 BIOS has been disabled (for faster boot up).
