is it possible to downgrade a g5 witch has a pre-installed 10.3.x to 10.2.8? the reason is a special drumscanner application, which only runs 10.2.8. some g5 model 7,2 would work, but are not in my surrounding area.any ideas to edit the installer, that he accepts a different hardware?
PowerMac, Mac OS X (10.2.x) , pre installed system is 10.3.x
Your G5 can use its original installer discs to install 10.2.7 or 10.2.8, and then you can apply the 10.2.8 update for G5 if all you have is 10.2.7.
Note, there are several options when doing this*:

Note also your G5 has room for a second SATA internal drive you can erase and install the original discs just for the application in question.
thanks for your reply. but it is a little bit more compilcated:
the machine i want to use is a "Apple Power Macintosh G5 2.5 DP (PCI-X) Identifiers: Mid-2004 - M9457LL/A - PowerMac7,3 - A1047 - 1969C"
this computer was delivered with osx 10.3.4 (7L18) and it is not possible to use an installer disk 10.2.7 to build up a new os. (this is what i think)
the question is how can i downgrade under the pro-installed os. i think "inside" the installer is a list with all computer, which are allowed to install. this should be edited.
or do you think it would work with an original installer disk for g5 powermac osx 10.2.7?
You cannot install a version of OS X earlier than the version the Mac originally shipped with.
downgrade ppc g5 under the pre installed osx
