Which is what I thought too!
<The having 2 instances of 'OS9 installation' doesn't cause any
problems. The hardware will only use one at a time, you may get to
choose, you may not, I don't know the 'built in' rules for choosing
an OS9 instance when there is more than one available and the
hardware is just looking for 'a' OS9 system.
In OSX System Preferences, choosing a OS9 system points the OSX
system there for running classic. [As I understand it, OSX then makes
some 'minor ?' changes to the OS9 system. But these changes are
supposedly benign as far as running OS9 directly is concerned.]
I believe that an opt/alt startup would allow access to both OS9
instances, never tried it, so I don't know.>
1. Okay. I have to reiterate my admission of being slightly confused at
the part of dc's suggestion that I should have TWO OS 9s installed on my
G4, one to run Classic with and one for booting/running OS 9. I learned
about folders having to be blessed to be bootable way before I even had
OS X, and simply installing the OS itself (7.x.x, 8.x.x, 9.x.x), from
floppy or CD whichever applicable, would result in an automatically
blessed System Folder which would boot the Mac you installed it on -- and
that was my primary experience with Mac OS installations. The blessing
business I learned about in conjunction with the idea of COPYING a System
Folder from one Mac (or HD) to another -- you'd have to bless the copied
one yourself to make that Mac or HD bootable (for a time I had two HDs in
my Beige, but that was in the last year of having the Beige before
getting the G4).
2. Yes, choosing an OS 9 System Folder from OS X's System Preferences
does make changes to that System Folder -- when you do it, OS X asks you
to "update." Update what specifically, I don't know, but apparently it
has to do something with running Classic. However, I have no idea what
making an OS 9 System Folder able to run Classic does to render that same
System Folder unable to boot and run OS 9, especially when it's on a
different HD from the OS X install, because:
For two years, the OS 9 System Folder on my 9 HD DID run Classic while I
was in Tiger, and ALSO booted and ran straight-up OS 9 when I did the
Option-Restart and selected the HD 9 was on -- once I did what I thought
was a clean install of OS 9 ("cleaning up" after the Beige). It's only
recently that this nice little dual bootability went south on me.
