I mean my MacMini. It comes with one "Mac OS 9 installation disc "and one "Mac OS X install disc 1 and apple hardware test". So, which one should I put?
*I should get myself a firewire. BTW, any idea how much does it cost?
Is that mean I can straight away insert the Mini's installation disc into my Imac? My Imac is PPC G4. And my Mini is PPC G4 too.
I'm sorry. I cannot understand this. What doesn't work with PPC?
Thanks for your help

A FireWire cable should set you back between RM10-20. Make sure you get the right one though. If I am not mistaken it comes in 4 pin (used in Sony products) 8 pin (Apple) variants for the FireWire 400 cables. To make things more complex, there are also the FireWire 800 cables but these are rather difficult to find locally.
I have no idea if your install discs will work on any other machine than the one it was intended for. My earlier post referred to the Mac OS 8 and 9 eras. Prior to System 8 the MacOS believe it or not was FREE.
Today I had to reinstall Tiger on my Titanium PowerBook (G4) as my wife wanted it to use as a Keynote presentation machine. I tried using the discs that came with my MacBookPro 2.4Ghz and my MacPro but both resulted in a kernal panic.
Luckily I had a retail copy of Tiger handy....
