![]() ![]() ![]() Resetting the NVRAM and all settings to default did not make any difference. I can only get to the OpenFirmware, it says Apple PowerMac 10,1 4.8.9f1 BootROM from 12/10/04. And when I replace the working HDD with another known-to-be-good IDE 40GB HDD and try to boot from another source like one of those CDs/DVDs I always end up in a blue/purple-ish like screen with a folder icon with blinking questioner/macos face. When I try all those keys like R, T, N, C, O, F, Ctrl, Alt, Option, Shift and all of their known combinations to alter the boot sequence, it never works. ![]() ![]() Now the problem is that except from booting the current OS from the original HDD, I am not able to boot from any other source. Now to my target! I want to boot from a CD/DVD or USB and IF that could be accomplished, I plan to replace the HDD with an adapter 44PIN IDE-to-mSATA SSD and put a clean installation on, 10.4.xx or 10.5.x. So I am ready and equipped to recover and reainstall the MacMini. Las thing to say, I have another fully operational hacintosh macbook made from a DELL Latitude 5400 laptop, available for creation of helpful CDs, DVDs, USBs etc. Next I already replaced the original DVD reader/CD writer model CW-8123-C with a GSA-T20N DVD drive and confirmed it reads the discs in the current OS fine. The legitimity and bootabiliy is unknown though. Plus I also another DVD with PPC Mac OS 10.4.6 Installation. However I was able to download&burn a set of 4 CDs with 10.4.2 and also download&burn a DVD with "OSX 10.4 Tiger Retail DVD". The only thing I dont have is the original DVDs or CDs or whatever the OS source that came with. I also obtained the password for the administrative account. It has an old USB keyboard and USB mouse with just one single global button being the whole mouse.Ĭurrently it runs OSX 10.4.11. It has 512MB RAM, 80GB IDE HDD and 1,42GHz PowerPC G4 CPU. Well, I recovered an old MacMini G4 (model A1103 from 2005) from an electronics' bin in our warehouse. ![]()
