Re:Update OS

[Janis Lynn]

Hi

A friend emailed me this question last night.  Could someone please  
answer it for me?
I just learnt that with my old iMac i can install OS10.2 if i  
wanted to,
but I would have to install some firmware programs to fix my iMac  
so it
will run OS 10.2. What firmware do I need and how  do it?

Thanks Guys

Janis
