Could anybody figure this:

I bought an old MacMini G4 / 1,25 GHz (model A1103) with Tiger (10.4.) preinstalled and wanted to update the OS to Leopard ( 10.5 ). For this I used a DVD from the Apple Store and at the beginning it asked for a firmware update, which I allowed.
After this process was finished the machine would not start up again.
I rebooted it from the original CD and used disk utility to repair the hard drive - of no avail.

How do I repair the firmware or restore it to its original setting?

Thanks a lot for Your kind attention Smile

Have you done a PRAM reset?

Yes, I tried everything, but it just would not even see the harddrive, for example when I try to reformat it... .

So, it does start up and you can get it to boot from the OS disc, but can't get any farther, right?

yes - it starts up from the system DVD and also from a firewire hard drive on which I have system 10.4 - but the internal HD can't be repaired or formated...
Would You have any idea of how to repair/restore the firmware - since I tried updating it the machine gave up running properly... .


Thanks a lot for Your attention!

If it boots from the external drive, then I would venture to guess that the internal drive has died. This just happened very recently with my G4 mini.

Glad to offer something resembling help!

The G4 mini is really a pain with the way it's engineered and all the stuff you have to do to get the drive out.

if he updated the firmware and he updated the firmware on the drive controller by accident the hard drive firmware is now trashed and the drive is dead this was a major issue with g4 mini's i killed 4 myself before figuring out that you want to upgrade the firmware on a fresh install of 10.5

Thanks a lot for YOur attention!

... does that mean that there is really no way out - maybe a trick ( via terminal or so ) of how to erase the firmware on the drive controller and put the proper firmware in?

you cant the drive itself has to reflashed to stock firmware the firmware is on the drive itself.

but the other issue is trying to find a replacement hard drive because the drive is not sata laptop hard drive but mini ide which is no longer being made so you have to find a used hard drive!!!

And the bad news if it's a seagate it would explain the reason why the hard drive failed to flash properly and the drive controller is having problems.

but in all do honesty even if you install mac os x 10.5 on this machine you have another issue the last powerpc version of flash player is 10.1 where the intel version goes to 10.2 and higher

so accessing the internet isn't going to go well on that machine you might want to think about purchasing a older thicker intel mini for your needs and reinstall 10.5 on that or even 10.6

Thanks a lot for Your expert advise -
I was hoping that anyone would know a trick - maybe via terminal - to reflash the HD - but apparently that does not work so easily... .

We use(d) the machine to automatically play music in our dairy at certain times during milking and on top of it used it once in a while for internet, etc..

But the suggestion to get a more advanced Mini sounds like the best solution, considering that time is also a valuable asset ...
