The grub menu is available and works, the kernel loads, the initrd step works, and then it hangs hard and requires power cycling. The required information for a kernel bug report can be found in Bug #1432659, from the original shipped F.23 bios. I obviously can't attach information with the F.26 bios loaded. I can confirm that the bios update worked, and I have repeated it twice. HP diagnostics give the system a green light, and I can boot to FreeDOS as normal. I'll leave the system unbootable with the F.26 bios for a while in case someone can help me diagnose further from grub.
