Hi,
i don't know whether it should goes to Support section or here, so if somethnig wrong, mods - i'm sorry and please move the thread to the proper place 
Ok, i've just bought few old macs, including PM G4 Digital Audio and iMac G3. They have one big mess on their hardrives so i decided to do fresh installation on each and put there a small collection of my old favorite games. I've downloaded few ISO images of OS9.1 but i'm not able to burn them properly :/ It does not matter which burn software i use (Burn, Apple Disk Utility, Nero, Toast), or if it's ISO, NRG, Apple IMG or even mentioned Toast file. I'm NOT able to boot such CD on real Mac later. Mac does not recognise it at all, but mounting them on OSX shows that all is right - there are system files and all seems to be completely OK. What am i doing wrong?


I've downloaded 9.1 Universal from location you've sent me.
