TCP/IP broken in Classic

[Jeff Rothfus]

I'm still struggling with my installation of OS 10.1 on an AGP graphics 
G4/350 tower.

I've run Norton SystemWorks, DiskWarrior, Disk First Aid and Repair 
Permissions, and I still have two serious problems:

[1] Native TCP/IP (internet) applications work great when booted into 
their native OS, either OS 9.2.2 or OS 10.1 --- but I can't get Classic 
applications (e.g. Claris E-mailer) which work great under OS 9.2.2 to 
connect to the the internet when running under Classic in OS X.  

The G4 is sitting on an Ethernet hub, and Classic apps don't show any 
activity light on the hub when running in OS X.  Native OS X applications 
(e.g. IE and Netscape) connect fine in OS X, and Classic applications 
connect fine in OS 9.2.2.

[2] I can't select an alternate Startup Disk when booted into OS X.   
When using OS 10.1's System Preferences 'Startup Disk' panel, the new 
selection doesn't "take".  To get back into OS 9.2.2 I must first boot 
from an OS 9 CD-ROM, and then use the CD-ROM Control Panel to select an 
OS 9 hard drive.

I would appreciate any suggestions.  I dread doing a full backup and 
clean install without first having explored every other avenue.

Thanks!
