You can. Read the ata man page (on the web site, if you have to): The hw.atamodes sysctl lets you set dma or pio mode for each individual device: sysctl -w hw.atamodes=pio,pio,pio,pio will turn them on for master and slave on both primary and secondary controllers (though it's not clear that that will work if there is no device attached at that point). If you can get to the point of launching the emergency holographic shell, you *ought* to be able to turn that on, and continue with the install. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
