Downgrading from the Mac OS X 10.2.8 Update to Mac OS X 10.2.6

Apple has posted suggested workarounds for the Ethernet-related 
problems introduced with the Mac OS X 10.2.8 Update in the AppleCare 
Knowledge Base document "Mac OS X 10.2.8: Can't Connect via Ethernet 
After Installing Update."

http://docs.info.apple.com/article.html?artnum=107669

If these instructions do not resolve the problems you are 
experiencing with the Mac OS X 10.2.8 update, you can downgrade to 
Mac OS X 10.2.6 using the following procedure.
You will need...

     * Your Mac OS X v10.2 Install Disc 1 and 2 CDs.

Procedure

(1) Perform an Archive and Install with the Preserve User and Network 
Settings option. See the AppleCare Knowledge Base document "Mac OS X 
10.2: About the Archive and Install Feature." [1]

http://docs.info.apple.com/article2.html?artnum=107120

(2) Repair Permissions from the Mac OS X v10.2 Install Disc 1 CD -- 
not the hard drive -- as follows:

     (a) Boot from your Mac OS X v10.2 Install Disc 1 CD.

     (b) When the Installer window appears, select Installer > Open 
Disk Utility from the Apple menu bar.

     (c) When Disk Utility opens, select your Mac OS X boot volume 
from the list of drives and volumes.

     (d) Select the First Aid tab.

     (e) Select the Repair Disk Permissions button.

     (f) After Repair Permissions completes, Quit the Disk Utility. 
Focus returns to the Installer.

     (g) Quit the Installer. When prompted, select Restart.

(3) Delete the Previous Systems folder using the instructions in the 
AppleCare Knowledge Base document "Mac OS X 10.2: How to Delete a 
Previous Systems Folder."

http://docs.info.apple.com/article2.html?artnum=25461

(4) Apply the Mac OS X 10.2.6 Combo Update. See the AppleCare 
Knowledge Base document "Mac OS X 10.2.6 Update Combo: Information 
and Download."

http://docs.info.apple.com/article.html?artnum=70174

(5) Repair Permissions using Disk Utility on the hard drive, per Step 
2 (Repair Permissions) of the Resolving Disk, Permission, and Cache 
Corruption FAQ.
Notes

http://www.thexlab.com/faqs/repairprocess.html

[1] The Applications folder is preserved -- copied intact -- as part 
of the Archive and Install process. However, per the AppleCare 
Knowledge Base document on Archive and Install, it states in the 
Notes section:

     3. Third-party software items that are installed within /System 
or /Library, or anywhere else besides a user's Home directory, are 
not preserved. Reinstall the third-party items after the Archive and 
Install is performed, if necessary.

Accordingly, you may want to review the article "Migrate to OS X 10.2 
with a Clean Install" from the October 2002 issue of Macworld for 
additional information, in particular the section therein concerning 
the Library folder. While this article was written to advise users 
upgrading from Mac OS X 10.1.x to 10.2, the additional details it 
provides on Archive and Install may prove useful for anyone using 
such.
