In installing System 7.0, I thought, to handle incompatable software, 
that I'd just partition my internal Apple HD 80 into 2 40 MB
partitions, install 7.0 on one, 6.0.5 on the other, and startup
on the 'appropriate' partition as needed.

In using the Sys7-supplied HD SC Setup from Apple, I find that, 
after creating one 40 MB 'Macintosh Volume' partition, that list
choice vanishes and I can't create any more 'Macintosh Volume'
partitions, so my plan won't work.

Is there anything I'm missing here?  	I recall, now, all the
discussion in comp.unix.aux, about how you could only
have a single Mac HFS partition usable on a hard disk, but I didn't 
think (obviously -) ) that that would happen here.

I appreciate any help. I could try using Silverlining, I suppose, 
but there was a posting a few days ago from a person who'd init'd
their internal Apple disk with Silverlining and now, when installing
Sys7, found that HD SC Setup couldn't find the drive to update it 
for VM, and (if I remember right) couldn't even re-init it with
HD SC Setup.

Again, thanks for any suggestions.  I'll forward info I get to people
who email me, or post to this group if enough people ask.

See you around the bit stream!
