What are you guys using for a kernel? This outb_p "bug" was fixed
in ancient times (or you didn't properly configure the kernel).

Yes, this works. It sounds like you are mixing the internal ATA hack
with card services. You can't use both........

That's right, no card services when I wrote that message. I just
used the PCMCIA interface as a dedicated ATA interface. The purpose
was simply to verify the hardware would work correctly, and to provide
a method for embedded systems to use this interface directly without
card services.
