How come I can't update OS X 10.1.5?

Hi there.....

Ok. I had reinstall my mac to its originally OS to what I had when I bought it years ago...

Now my O/S is OSX10.1.5 (I just do a combo update from OSX10.1.2 to OSX10.1.5, and also with OSX9.2.2) I had the OSX 10.3 (panther) installation software with me and I want to install it, but the Operating system got to be in OSX10.2...right? And I also can't find any link for downloading of update software from OS X10.1.5 to OS X10.2 from apple website...

Anyone can help me.....pls...

There is no update from 10.1.5 to 10.2.x.

10.2 is a whole new upgrade that must be purchased. Same goes for 10.3 and 10.4.

If you have a set of 10.3 install discs, then you should be able to simply install from them and be fine.
