So I'm trying to install OS9 on a tray loading imac. I intially load 9.1 onto the machine, and all is well. I install Appleworks,reboot, then do the update, reboot abain. Well, it doesn't boot any more. I run diskwarrior. Corrects a few things, no biggie. I reboot the machine , nothing. Still the flashing question mark. So I boot from the disk, zero out the data (again), then reinstall the OS, taking care to reinstall the HD drivers. No luck. Everything in on the hard drive, the system folder is blessed, but I will not boot from the disk any more. Anybody have an idea what's wrong??
