The chip select stuff is default from the reset at this stage, and I really have no intention of touching it. As you can probably imagine (or have read by now), this is a pretty bare-bones BIOS. There's not really a whole lot in there to play with, at least as relates to boot devices. We're pretty much out of knobs to turn at this point; DMA settings are about all that's left. I've posted a (fairly lousy) cameraphone shot of the screen in question at http://tinypic.com/r/9lbdcg/6 in case there's anything useful I may be able to try that I'm not thinking of.
