I added the following to /etc/modules: snd_aoa_i2sbusĪs a result there is now a sound card listed in settings:īoth in settings and ALSA the device can be edited. What I have is a nf and seven more blacklists in this directory, but none of those seems to adress sound. The PowerPC FAQ says the file /etc/modprobe.d/ should be deleted, but I do not have such file on my system. Alsamixer crashed when selecting Edit » Sound Card Properties obviously because there was no sound card recognised. Regarding sound I had the typical phenomenon with "dummy audio" being said and no audio device listed in system settings. Everything looked and worked pretty well after installation, with the exception of sound and WiFi. I recently installed Ubuntu MATE 16.04 on my G5 PPC, dual booting with OS X 10.5.8. But these solutions do not work for me / on my box. It might as well be USB manufacturer related.I am aware that the sound issue with PPC G5s (PowerPC) has been discussed in quite a few posts in several forums and communities and it was marked "Fixed". For me, the final working path was If it still doesn't work make sure your USB pendrive is at least 8 GB in size - I didn't manage to boot from any device smaller than that - as Open Firmware appears to require that. The fix is surprisingly simple - try swapping the USB port you plug your USB drive into and updating the devalias ud accordingly until it works. Congratulations! You're doing good - you've managed to boot into the Open Firmware and set up the boot device, but it appears not to be working. Unless you left your machine's mainboard compartment open (without the translucent polycarb air guide). Try getting another keyboard and verifying that your machine is actually working correctly - if there's a red led lit (or flashing) on the main board you might have a hardware issue. If you did not reach the Open Firmware step - tough luck. You can set auto-boot? back to true now.) Troubleshooting (In the rare event it actually did work - you're done. aaaand if your luck is anything like mine, it won't work. If you still didn't manage to boot into the Open Firmware consult the Troubleshooting section, otherwise make sure your machine always boots into the Open Firmware:
If you fall into the first category - congratulations, you can now wear your smug smile until the end of time, otherwise - don't get discouraged too quickly thanks to the following instructions you'll only have to do this once - for me it was more like five or six times. Try several more times while swearing a lot and randomly pressing and releasing the key combination.Get awfully discouraged with the whole enterprise.Fail to reach the Open Firmware screen a few more times.Try pressing the combination right after you hear the initial boot up sound.Fail to reach the Open Firmware screen.Fail to reach the Open Firmware screen several times.
This process might be quite random and nerve-racking unless you own an Apple-issued wired keyboard. Now here's the fun part - we'll need to boot into the Open Firmware in order to change the boot sequence. Now you can plug your USB drive in the PowerMac and proceed to the next section. This varies from platform to platform so unless you're using GNU/Linux you'll have to google. PreparationStart off by downloading an image (let's call it image.img) and burning it onto a pendrive. preferably wired preferably Apple keyboard,.a USB pendrive, at least 8 GB in size (more on that later),.PowerPC-flavored GNU/Linux distribution image of your choice (I used Ubunt 16.04 LTS but these instructions should apply equally to any other distribution),.
In fact, you can download a live ISO image of the most recent version ( 16.10 at the time of writing this post) right off the official Ubuntu downloads page. Surprisingly enough, even though Ubuntu has dropped the official support for PowerPC quite early (since 7.04), there's a strong community still maintaining PowerPC ports of the distro & various packages.
I've decided to write this post because these machines are getting old and any sort of info on how to boot GNU/Linux on them is getting sparser by the year. The machine in question is an early model of double-processor PowerMac G5, version 7.2 to be exact: Recently, I had a craving for some PowerPC action, so I dug up an old PPC970-based machine and had some considerable fun playing with it.
