I've been working on the pdc202 driver having had some problems getting my new
gigabyte MB running sweetly. The following patch fixes the configure help to
be, well, more helpful. I hope this is useful.
In the text, I have referred to the two configure options I have renamed in
another patch that I'll be submitting tonight also. These can, of couse, be
left as-is.

This driver adds up to 4 more EIDE devices sharing a single
interrupt. This add-on card is a bootable PCI UDMA controller. Since
multiple cards can be installed and there are BIOS ROM problems that
happen if the BIOS revisions of all installed cards (three-max) do
not match, the driver attempts to do dynamic tuning of the chipset
at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required
- for more than one card. This card may require that you say Y to
+ for more than one card, and this card may require that you say Y to
"Special UDMA Feature".
+
+ If you have a RAID-capable controller, such as the PDC20276, it will
+ be used as a plain IDE controller unless you say Y to 'Do not use
+ software RAID device as plain IDE controller' and also say Y to the
+ Promise software IDE RAID controller. If you do this, the IDE driver
+ detects the controller during startup, but ignores it.
If you say Y here, you need to say Y to "Use DMA by default when
available" as well.
