No, there is a different piece of the inital install. I think it is for
certain Quantum drives. I've never had to use it, so I didn't pay too
much attention to when it is needed.

I don't know what I'm referring to for FPU emulation. I just know I've
seen messages about it pass thru the mac68k email list. Since I don't
have any machines runing NetBSD that don't have an FPU, I've never paid
much attention.

I thought it was something on the netBSD side, but it could be a MacOS
side thing for all I know.

Yup, and thus why when I was tossing some broken macs with full 040
chips, I pulled the chips to swap into things like my Centris 610's and
650's. That way, I can use them for mac68k later and not have any FPU
headaches.

I'm sure I still have a chip or two kicking around, so all John has to do
is ask, and I'll be happy to send him one to swap into his 575 (if he is
still using the 575 and in fact needs one. I can't be sure that I didn't
do the swap before giving him the machine, but I don't think I did,
because I don't think I knew he was going to use it for NetBSD).
