Strange behavior of my PowerMac G5 - it doesn't boot anymore

February 28, 2026 — Jan Montag

Anyone who reads my blog from time to time is familiar with my PowerMac setup. I have two SSDs connected to the internal SATA ports: a 512 GB SATA SSD for Mac OS X 10.5 and a 128 GB SSD for Linux. I also have an NVMe SSD connected to the internal PCI Express x4 port.

Long time not seen...

Dear friends of PowerPC Linux, Unix and especially the Powermac G5, I've not written since quite a time. The reason was my other Webproject [¹] which I managed to melt with another Website and beside that, move it into a Docker Container and run it and adopt everything and so on and on and on... you know - from stick to wood like someone says. :-)

Speed of light - NVMe SSD in a Powermac G5

I told you the other day that my PowermacG5 owns an NVMe-SSD-Adapter as a PCI-Express Card with a 1 TB NVME-SSD. That runs great, here is the Benchmark:

/dev/nvme0n1:

Yes, 1129 MB/Sec, bäm!, this is what PCIE 1.0 4.0 Slot can do. :-) Nicenstein, in a 2005 Computer.
