Tried to install Tiger Server software from 2 shipped cd's (no dvd drive on the machine) on a Test machine in my office to see how it works and get familiar with it. (System only running on this machine, no data or other apps, not a main workstation.) What a wretched idea! It's a G-4 Digital Audio running 10.3.6 Server software with a small RAID attached; had 57 Gb free on 60gb hd-- has been running fine. Initial Upgrade install failed--froze after a few minutes on Disk one. On Restart- got Kernel Panic text message Restarted and ran Repair Permissions in Disk Utility as well as Repair Disk--seemed to be fine. Rebooted and proceeded to do a Replace/Erase install-- (Upgrade not an option anymore.) "Installation cannot be completed" error after one minute. Clicked "Restart" option from cd install disk and noticed the system software showing up on computer was now 10.4 (even tho installation failed.) On Reboot, (with 10.4 install cd still in cd bay) got blank gray screen Powered down and detached RAID--no other peripherals attached. On Reboot, holding down "C" key (with 10.4 install cd still in cd bay) got folder with ? mark Tried to eject cd from keyboard and by pushing tray button, Will not budge On Reboot, with 10.4 install cd still in cd bay, got blank gray screen On Reboot, started up from Firmware and tried Command line "eject cd" - would not work - froze. Tried starting up with Shift key--Nada--gray blank screen Could not eject cd--inserted paper clip. Manually ejected and inserted 10.3 Install disk. Reboots to folder with ? mark holding down "C" key I noticed that the cd light never goes green--blinks amber. Can;t hear any spinning. Still can't eject cd. Paper clip not working now. Hmmmm....I wonder if the optical drive has failed. If it IS the cd drive--will attaching an external cd drive work? Never tried to reboot from an external drive. Any thoughts?
