I have received several conflicting pieces of information as to whether I can load up an early G4 (400mhz) silver tower model solely with OS9.

Castlereagh School needs to run OS9 for their educational software and would prefer not to have the OSX /classic setup. Can I install OS9 as the sole operating system?

TIA

IF it boots off an OS , it will run on that OS installation without the other !

Dual boot was available up until about 2002 .. forget the exact model ,
but your is well before that.

IF .. the Mac has SCSI    &  ADB  then OS9.1 will work best .

IF .. the Mac has been manufactured with USB, or USB and Firewire ... OS9.2 is your system .

Hope that helps
