I did run molvconfig. I just ran it again to make sure, and tested 
every single video mode available. No dramatic change in my results.

However, when I say "blank black screen", I mean that the video seems 
to shift into console mode, but nothing after that. What is worth 
nothing, though, is I do see the end ("*** DONE *** ") of the video 
probe on that screen, if I've run the probe recently.

Hmmm. I don't know that I have a strong preference on window vs. full 
screen. Right now, I'd just like to get *something*; I can wrestle with 
preferences after.

I can try that.

The hfsutils seem to be installed. I can hmount it, but nothing shows 
on an ls. That's a little weird, but I guess I don't know that hfsutils 
is supposed to be able to read the drive... ?

None of the MacOS/hfs partitions are mounted at boot, neither are 
listed in fstab. None of them have been mounted when I tried startmol. 
(Though, if you're looking back in the thread, there was a while there 
where I didn't have an HFS partition *at all*.)

Thanks for your help!
