OK, here's the problem. I have an iMac DV400 currently running Jaguar with no System 9.1 on the HD. I'm trying to install Panther but the installing tells me I need to update the iMac firmware. I went to the Apple Support site and downloaded the firmware update installer but when I tried to run it I get a message that I need to be in system 9 to begin the install routine. So I think I need to erase my hard disk, install 9.1 then do the firmware updater and finally install Panther. Am I correct? Or am I missing a step here? Thanks for any help Bob
