Help!
I was playing around with installing NetBSD, and I've got something going 
on now that keeps it from working...

I can go through the entire install procedure, including newfs'ing and 
fsck'ing ra0a (I've got a single drive, RD54).  But, as soon as I try to 
mount ra0a on /a (per instructions), I get messages like, "bad dir... " 
and some other stuff, and it crashes the machine.
It worked the first time, so what do I have to do to get it to work again?

PS, I'm installing from a TK50...

thanks,
Jonathan
