Yeah, that is what I ended up doing. The problem was that the only kernel
I had access to (koth-generic) defaulted to using wd0a as the root
partition, so when I booted using the -r flag (use the kernel's compiled
in partitions), I would get a panic when it couldn't find wd0a. The
solution was to use a specially compiled kernel (thanks again!)
compiled with "config netbsd root on sd0a swap on sd0b", or use the -a
flag (ask which partition to use).
I would suggest that some of the more useful boot flags (at least -a) be
listed in the INSTALL docs.

The specially compiled generic kernel was 1.3Mb, and boot.com worked fine
with it. I can't imagine compiling a kernel bigger than that!
