I, too, have 32Mb and an aha1542.  I hacked machdep.c to limit my
memory to 16 Mb, but am basically swapping constantly.  Can you say
something about how different OpenBSD is from NetBSD and how hard it
was to switch?

First, is it possible to run an OpenBSD kernel with the rest of the
system (including init, ps, netstat, etc.) from NetBSD?

Failing this, is it possible to build and install OpenBSD from a
NetBSD system?  I presume all my /usr/local and /usr/X11R6 software
will also still work under OpenBSD?  Will stuff compiled under OpenBSD
also run under NetBSD?

Alternatively, where are the bounce buffers implemented in OpenBSD?  I
downloaded the actual aha1542 driver but it was identical to the
NetBSD one.  Is there some piece of code from OpenBSD that I can drop
into the NetBSD kernel?  (I don't care how inelegant it is--I need to
stop swapping!)

Thanks,
David
