I own a MAC (Aqua) G3 / 400Mhz / 256MB RAM / 12.0GB HDD system that I
bought used...it came configured with 8.6 (I have the original CD's)
upgraded to 9.1.  How can I configure it to be dual boot with both X
(10.1) and Classic (9.1)?  Being a relatively new MAC user I purchased
a couple of the Missing Manual line of books that seem to be very
informative, but it gave precise instructions on how to format,
partition the hdd, and install X (10.1) but it left me hanging on how
to get the Classic installation.  Having purchased the system used I
opted for the suggested format and partition process...of course
formatting the drive deleted the old OS which is fine or at least I
thought it would be OK to start fresh...if I had known it would be
this difficult I would not have formatted the drive.   I was under the
impression that you could upgrade to 9.1 from 8.6 but when I booted up
holding down the C key (during my second attempt at configuring a dual
boot MAC) when I attempted to get to the 6.0GB partition for the
Classic the 8.6 OS didn't want to install...it gave error code 1012 -
operation could not be completed.  My goal is  to have both X (10.1)
and Classic (9.1) happily residing on their own partition on the same
hdd, but at this point the upgrade process is every bit as difficult
as upgrading Windows...actually XP was easier.  What process do you
suggest to configure the dual boot system?

Hello nokri,

Mac OS X comes with Classic mode, and it does appear that my ibook
came with both preinstalled and this might also be the case for you if
you used the default installation. Try these instructions to see if
you have Classic installed and just need to activate it now:
http://kb.indiana.edu/data/ajel.html?cust=769497.28547.131

If the first idea did not work for you, at this point I would like to
try and figure out where we are and work ahead from there. This
AppleCare Knowledge Base Document will be helpful in finding a
solution for this problem:
http://docs.info.apple.com/article.html?artnum=106678

If after trying to Start Mac OS 9 (Classic) using the instructions
above and you receive one of these error messages,:

ERROR 1: "To start Classic, you need Mac OS 9.1 or later installed.
See your documentation for instructions on installing this software."
ERROR 2: "No startup volume. There is no volume with a system folder
that supports starting Classic. Please install Mac OS 9.1 or later."
ERROR 3: "You do not have sufficient permissions to run Classic from
/System/Library/CoreServices. Please correct permissions and restart
Classic."
ERROR 4: "Cannot launch Classic, Classic Boot ROM missing or damaged,
reinstall system software."

the culprit in this case is probably the fact that there was an option
during the installation of OS X that was not checked that would have
installed Classic.

From the Apple Document: "To determine whether or not Mac OS 9 is
installed, open the System Preferences application and click Startup
Disk. Any valid Mac OS 9 System Folder appears in the window. If no
Mac OS 9 System Folders appear, you must install Mac OS 9 from the
CD-ROM disc included with Mac OS X. If you do find a System Folder,
continue to the next section."

If you see the Mac OS 9 System folder, but are unable to get into Mac
OS Classic, try Solution 2 on this page:
http://docs.info.apple.com/article.html?artnum=106678

I do believe that installing classic is extremelly difficult if one
installs OS X first WITHOUT classic (see this thread for one example:
http://www.suspicious.org/pipermail/tm/2003-March/000081.html) I do
not understand why a default installation would not have automatically
installed classic mode, and hopefully this is just a matter of getting
classic mode started for the first time. If you definately do not have
the Classic folder on your drive, please let me know and I will give
you some instructions on how to reinstall OS X with Classic mode.

Please let me know if you run into any problems with this solution, or
if you have any further questions. If possible, I would also like to
hear from you what the actual problem was and which of the methods
above worked to fix it. I will do my best to help you work through
this problem so feel free to ask for Clarification if anything springs
to mind.

It appears that the answer will provide the proper process once the
MAC OS 9.2.2 CD-ROM arrives from Apple...I can't really proceed until
then and I will not know for sure that it works until that time. 
Thanks

Additionally Mac OS-X works best with OS-9.2.2 which is a free upgrade
from 9.1 as mentioned from this Apple page
http://docs.info.apple.com/article.html?artnum=106434&SaveKCWindowURL=http%3A%2F%2Fkbase.info.apple.com%2Fcgi-bin%2FWebObjects%2Fkbase.woa%2Fwa%2FSaveKCToHomePage&searchMode=Assisted&kbhost=kbase.info.apple.com&showButton=false&randomValue=100&showSurvey=false&sessionID=anonymous|169510152

Download from here and follow the sequence of installation (9.2.1 and
then 9.2.2)
http://docs.info.apple.com/article.html?artnum=75288

From my own personal knowledge it's best to install OS9 first prior to
installing OS-X, the latest free upgrade you can go to is 10.1.5
http://docs.info.apple.com/article.html?artnum=106713&SaveKCWindowURL=http%3A%2F%2Fkbase.info.apple.com%2Fcgi-bin%2FWebObjects%2Fkbase.woa%2Fwa%2FSaveKCToHomePage&searchMode=Assisted&kbhost=kbase.info.apple.com&showButton=false&randomValue=100&showSurvey=false&sessionID=anonymous|169510152
(you MUST install in the order listed starting with the base of 9.2.2)

Summary:
install 9.2.1 > install 9.2.2 > install 10.1 > install 10.1 security
patch > install 10.1.5 > install 10.1.5 security patch

You can chose to boot into OS 9 or OS-X ,by selecting either system in
the 'Startup disk' icon in the control panel of OS 9, or the
preference panel of OS-X.

If you run a classic (OS 9) application in the OS-X environment it
will automatically launch OS 9 in the background and run the
application in the OS-X enviroment. You will probably only need to
boot into OS 9 if you need to use some peripherals which do not have
OS-X drivers or to install some OS 9 applications (those installers
that do not run in the OS-X environment)

You didn't actually say if you had installed OS-X, as the Mac 'may'
also need a firmware update but couldn't find any tech documents in a
quick search... but it should mention it in the install documentation
if any firmware update is required.

Good luck.

I tried many of the suggestions that were good, but clicking on the
Classic 9 icon within the OS X system folder gives the no start-up
volume error message.  At this point I would be happy to start from
scratch again just so I can get it taken care of so it will be a fully
functional dual boot X (10.1) and Classic (9.1) MAC.  If I start at
the beginning again and re-format the hdd and partition it into two
6.0GB partitions how do I get OS X on one partition and Classic on the
other...of course where they will both recognize each other.  I am
also concerned that for whatever reason once 8.6 is installed that I
will not be able to successfully upgrade to 9.1 and then 9.2.1 and
then 9.2.2.  My copy of 9.1 is what appears to be an upgrade disk not
the full standalone version...so it would appear that I will have to
start with 8.6.  Back to the question of whether or not you can
upgrade to 9.1 from 8.6?

In answer to the last query:

Mac OS 8.6 cannot be upgraded with an OS 9.1 updater.  OS 9 is what
Apple calls a "reference release," meaning that it is considered a new
product.  While OS 9 can be installed over OS 8.6, it is not
considered an upgrade.  Thus the OS 9.1 update CD you appear to have
can only update existing OS 9 installations.  If you can find any OS
9.0.x install CD, you can install from it to provide the foundation
for the 9.1 update.  OS 9.2.2 is recommended as your final
destination, as a previous commentor mentioned.

Mac OS 9 and Mac OS X may both be installed on the same partition,
providing both dual-boot functionality and the ability to run Classic
when booted into Mac OS X.  The most direct way to achieve this:

- Reformat your hard drive.
- Install some version of OS 9 on the drive.
- Update the OS 9 system as far as possible.
- Install OS X on the drive.
- Run the Software Updates check from System Preferences over and over
until it tells you there are no more available updates.
- Go to the Classic pane of System Preferences.  A Classic startup
system should be available.
- The first time you launch Classic, expect to get a warning that the
OS 9 system must be slightly modified to support running inside of OS
X.

A benefit to using separate partitions for OS 9 and OS X is that OS X
is essentially impossible to uninstall.  If you ever have to rebuild
your OS X system, you must reformat the partition on which it lives.

In short, OS X can use any OS 9 system on a local volume to run
Classic.  If it's not working for you, likely your OS 9 system is at
fault.
