The issue/problem of having system folders on the first 8GB was limited to
only the iMac rev A-D. The slot loaders do not suffer from this limitation.
The problem could be similar to two problems documented in the Applecare
Knowledge Base: article ID 106639, and article ID 106678. The problem may
simply be that of an "unblessed" system folder. The articles are quoted
here:
" 106639:
TITLE Mac OS X 10.1: "You are running Classic without superuser (root
privileges)" Message Article ID: Created: Modified: 106639 1/3/02 8/1/02
TOPIC
This document explains how to resolve a potential issue in which the
Classic environment does not start up, giving you an alert message about
"superuser (root privileges)".
DISCUSSION
Note: This technical document covers one aspect of troubleshooting
the Classic environment. For more information, see technical document
106677: "Mac OS X: Troubleshooting the Classic Environment
<article.html?artnum=106677>"
Symptom
An alert box with one of the following messages appears, and Classic
does not start up:
"You are running Classic without superuser (root
privileges). Ensure that TruBluEnvironment is setuid and owned by root, or
reinstall your Mac OS X System Software."
Note: If you see this message when using Mac OS X 10.0, see
technical document 106278: 'Mac OS X 10.0: You are running Classic without
superuser (root) Privileges' Message <article.html?artnum=106278>"
Products affected
* Mac OS X 10.1
Solution
1. Open System Preferences.
2. Click Startup Disk.
3. Select your Mac OS 9 System Folder in the Startup
Disk pane.
4. Choose Show All from the View menu.
5. Click Classic.
6. Select your Classic startup volume (the one that
contains your Mac OS 9 System Folder).
7. Click Start. Classic should now start up as
expected.
8. Choose Show All from the View menu.
9. Click Startup Disk.
10. Select your Mac OS X System Folder in the
Startup Disk window.
11. Close the System Preferences window.
If the issue persists, use the Repair Privileges Utility.
Your system must be updated to Mac OS X 10.1.5 before using this utility.
For information and software download, see technical document 106900, "Mac
OS X: About the Repair Privileges Utility <article.html?artnum=106900>".
Notes:
1. The Classic System Folder may not work if
required software components have been removed from it. In this case, the
System Folder will not be a choice in the Startup Disk control panel. If you
have this symptom, go to Solution section "B" of technical document 106426:
"Mac OS: 'Startup Disk no longer has a valid System Folder'
<article.html?artnum=106426>"
2. For best results, do not install multiple
versions of Mac OS 9 on your Classic startup volume."

TITLE Mac OS X: Classic Will Not Start Up - Mac OS 9 Not Installed or Not
Blessed Article ID: Created: Modified: 106678 1/22/02 5/23/02
TOPIC
If Classic will not start up, Mac OS 9 may not be installed, or the
Mac OS 9 System Folder may not be "blessed" or active.
DISCUSSION
Note: This technical document covers one aspect of troubleshooting
the Classic environment. For more information, see technical document
106677: "Mac OS X: Troubleshooting the Classic Environment
<article.html?artnum=106677>".
Symptom
Classic will not start up at all, or the Classic startup process
fails. An alert box with one of these messages appears:
* "To start Classic, you need Mac OS 9.1 or later installed. See your
documentation for instructions on installing this software."
* "No startup volume. There is no volume with a system folder that
supports starting Classic. Please install Mac OS 9.1 or later."
* "You do not have sufficient permissions to run Classic from
/System/Library/CoreServices. Please correct permissions and restart
Classic."
* "You are running Classic without superuser (root privileges). Ensure
that TruBluEnvironment is setuid and owned by root, or reinstall your Mac OS
X System Software."
If you see the first, second, or third message, use the
solution in this document. If you see the fourth message, stop here and go
to technical document 106639: "Mac OS X 10.1: "You are running Classic
without superuser (root privileges)" Message <article.html?artnum=106639>"
Products affected
* Mac OS X 10.0 and later
Solution
There are two causes for these messages.
1. Mac OS 9 is not installed on the computer
Since Mac OS 9 is not necessary for the operation of Mac OS
X, you may not have installed it. However, to use Mac OS 9-compatible
applications in the Classic environment you must install Mac OS 9. 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.
2. No "blessed" Mac OS 9 System Folder
The Mac OS 9 System Folder may not be "blessed" by Mac OS X.
A System Folder is said to be "blessed" when it is recognized by the Finder
as valid and active. Open the System Preferences application and choose
Classic from the View menu. When none of your volumes contains a blessed Mac
OS 9 System Folder, all the volumes appear dimmed. You may see an alert box
with the message:
"No startup volume: There is no volume with a system
folder that supports starting Classic. Please install Mac OS 9.1 or later."
It may not be necessary to reinstall Mac OS 9. You may
simply need to "bless" the existing System Folder. Follow these steps:
1. Choose System Preferences from the Apple Menu
2. Choose Startup Disk from the View menu. The
Startup Disk pane appears.
3. Note the current Startup Disk selection, which is
a Mac OS X volume.
4. Click the Mac OS 9 System Folder you want to
bless.
5. Choose Show All from the View menu. A sheet
appears to confirm your choice in Step 4.
6. Click Change.
7. Choose Startup Disk from the View menu.
8. Reselect the volume you noted in Step 3.
9. Choose Show All from the View menu. A sheet
appears to confirm your choice in Step 8.
10. Click Change.
For more information on reblessing your System Folder, refer
to technical document 106426: "Mac OS: 'Startup Disk No Longer Has a Valid
System Folder' <article.html?artnum=106426>"
Try either.
Apologies in advance for the length of this reply.

Yeah this seems loggical, but doesn't this apply to the Rev. A-D iMacs only?
H�l�ne or Marc says it is a 350 Mhz, so this is a slot-loader.
I think that H�l�ne or Marc has to check the Classic pane in the System
Prefs
and see what is selected there, ann perhaps if she can find anything
strange.
Also H�l�ne or Marc make sure that you haven't disabled some Classic System
Extensions from your OS 9.2.2 System Folder such as 'Classic', 'Classic
Support' and 'Classic Support UI'.
