Since none of my boxes are affected by the current xz desaster, I spent the day fighting with a CF-to-IDE adapter in my retro PC.

OS/2 2.1 and 3.0 just won’t boot from a CF disk, they’re stuck at (or before?) the boot loader, completely silent, nothing happens, nothing on screen. MS-DOS 5.0 on the same CF disk boots just fine, though, as does the exact same OS/2 2.1 installation from a hard drive.

Hm. 🤔
