for x86 or PowerPC?

Talking about rabbit-holes. I used to have prototype OS/2 PowerPC 64-bit hardware from IBM before they killed the project. I should have kept that early EFI-based system. When the EFI boot sequence would panic, you would get an error message of "Danger Will Robinson".

man OS/2 Warp on PowerPC should be really secure because no one is writing malware for that combination!
