I have a CKD file, created with the Hercules dasdinit program. It's a (hercules) 3350 uncompressed file. I've put a small "hello world" IPL program on it, and it works fine with Hercules
When I try to run it with qemu-system-s390x I get : LOADPARM=[ ] Using virtio-blk. Using guessed DASD geometry. Using ECKD scheme (block size 4096), CDL No zIPL section in IPL2 record. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< zIPL load failed. Could not find a suitable boot device (none specified) Failed to load OS from hard disk The qemu script is : qemu-system-s390x -m 16 -drive format=raw,file=test-ipl.3350.un,if=virtio -nographic I found this link re: the zipl command. https://www.ibm.com/docs/en/linux-on-systems?topic=u-modes-syntax-overview Where is that command and / or its source ?
