Installing MorphOS on IMac G5

MorphOS is an operating system inspired in AmigaOS for PowerPC platforms. It's proprietary based on some open source components. You can install it freely but will stop working after 30 minutes unless a license is purchased. I recently installed it in my old iMac G5 to give it a shot. Installation from a USB drive is not a hard process, although not free of nuances.

1. Download the image morphos-3.15.iso from https://www.morphos-team.net/downloads.
2. Copy the iso file into a FAT32 formatted USB drive.
3. Mount the iso file and copy the file mac_ppc64/boot.img back to the root of the USB drive.
4. Restart iMac and hold cmd+alt+o+f during boot to access the openfirmware console
5. Boot from the usb by entering: boot ud:,\boot.img bi umsd0:morphos-3.15.iso
6. Go through the MorphOS installation.
7. Restart the iMac and go back to the openfirmware console with cmd+alt+o+f
8. Check the nvram environment variables with printenv
9. Validate the bootinfo file is in the hd: device with dir hd:,\\
10. Set the default boot device to MorphOS with setenv boot-command boot hd:,\\bootinfo.txt
11. Shutdown with shut-down or reset-all

Have fun!
