Hi, I'm having access to my old XT for next couple of days so I decided to give the latest ELKS a go. Since I still don't know how to boot it from CF-IDE card (I can boot FreeDOS from it), I'm still booting it from 360k floppy. Unfortunately, nowadays it only prints MINIX and reboots itself after a while. I managed to make it boot again after reverting following commits on master: 93b57f474cb0e3fa9917b4783781cd405c944b04 [libc] Data segment starts with nil data 9e038b816014f83c0808df1ee5697380cd6be499 Revise bootblocks for GCC-IA16 (the first one is reverted mostrly to reduce conflicts when reverting the other one). I guess something went wrong with implementing new features. Cheers, Paul
