You really did disklabel /dev/sd0c, didn't you?

UNIX boot? Is that the swap partition?

It is a bit frustrating, isn't it. But after a while, and copious use of
nenscript (to print text files 2-to-a-page), I've managed to get by.

Check out the Red Book, the Design & Implimentataion of BSD 4.4. Note,
I'm paraphrasing the title. It gives a good overview, and helps make
