I've trying to run Fedora-Workstation-Live-x86_64-32-1.6.iso

It kernel panics with the message that it attempted to kill init

In the former case, it gives exit code 0x00000009.

Have you updated the BIOS? See: [SOLVED] (Linux Mint 19) Kernel Panic on HP Compaq dc5800 Small Form Factor PC

For several months,
I've been running Centos 7 with no difficulty in booting,
except for needing acpi=off .
I've needed that on every computer I've ever owned.
I know roughly what it means,
but have no idea why it would matter.
The live DVD, including Troubleshoot, crashes with or without acpi=off .

How do I boot?
