So this seems specific to NetBSD / qemu? For reference, this is the image I tried in all cases: http://netbsd.mirrors.hoobly.com/NetBSD-7.2/iso/NetBSD-7.2-sparc.iso and this is the command I ran: qemu-system-sparc -M SS-5 -m 256 -nographic -drive file=NetBSD-7.2-sparc.iso,format=raw,if=scsi,bus=0,unit=2,media=cdrom -boot d Cheers, Malte
