I have just committed a rather hacked up driver for the ATA100/kauai
ide controller in the newer macs (PBG4 12/17, PowerMac G4 1.24/1.42, imac???)
The driver has support for UDMA mode, but I do not have the proper
settings for the various speed drives, so DMA modes are currently disabled.

If you have access to machines which have this ide controller in it
you are encouraged to test this and send results with dmesg to me.
Hopefully the driver can be cleaned up and DMA modes enabled soon.

Hey, this looks like it should be a big help to all of you OpenBSD-macppc people out there. Please test this patch and help Dale refine it.

      yeah, took a while! wonder how comes you couldn't beat him to it and send a driver months ago!

      Considering he just got a machine with that chip, he did it pretty fast. Dale does excellent work, and did all of this with no documentation.

        Yeah, gotta admit that's impressive.

      If you've got a problem with how long things take, then start contributing.

    Is there a snapshot of this already? Otherwise it is a bit of a chicken and egg problem for me. Can't really install OpenBSD without having an IDE driver :-)
