Wrong.  Startup Disk does not tell which hard partition on a drive
to start up from, only which *physical* disk, at least on the IIci I
have at work.  It also doesn't work on a Plus, which is what Rajiv
mentioned he has.

The proper procedure is to install 6.0.x on one partition, 7.0 on
another, and then rename the partitions based on which system you
want to boot up with.  I have been doing this for months, and it
works.  The drive boots up from whichever partition is first in
alphabetical order.

This is true.  The problem can be avoided if you use the Desktop
Manager INIT under 6.0.x.  DM is available on ftp.apple.com in
dts/hacks/oscar.hqx or thereabouts.
