I think you're referring to where you have to
hand-install the packages for
drives >1GB in size due to an Installer fault. There is a way to do this
manually (because when I first built and installed 1.4.2 way back when on my
IIci, I had to do this on the 2GB main drive), but sysinst with 1.6.2 is so
good and so seamless that you should just jump to 1.6.2 and use the sysinst
kernel to do the installation. It's very, very easy. Drag the MacOS-based
Installer to the trash and fergeddaboudit.
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.
If you're referring to SoftwareFPU, this only works
in MacOS, and only then
because of how Apple implements SANE.
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.
There is an experimental 2.0 -msoft-float kernel and
people have reported
good success with it, but my recommendation has always been that if you can
upgrade the machine to a full '040, just do it and use the stock kernel.
I'd reserve -msoft-float only for machines where this is not possible, like
the Blackbird PowerBooks, for example.
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).

Ohhhh -- you mean the GENERICSBC kernel. This is a polled SCSI kernel and
has somewhat poorer performance, and should be used if there's evidence of
SCSI issues or known filesystem damage (i.e., it would not be first on my
list to use). The Quantum connection is that it seems (seemed? haven't heard
much on this bug in ages) to happen more on certain Quantum drives, but it
doesn't occur on all models, nor does it necessarily occur on the affected
ones, and nor is it specifically limited to Quantum drives. Again, I haven't
heard much about this bug for a very long time.

The Mac's current chip is a XC68LC040RC33B.
I have a spare chip here, a XC68040HRC25M
which looks the wrong speed.
Yup, count me in.
Thank-You.
