AFAIK, the 3.1 ROMS have a CD filesystem
No Amiga ROM have cd filesystem (except CDTV and CD32 extra ROM).
AFAIK the only way to boot from CD is to use Phase/DCE board with CD filesystem on flash (for example CyberStorm PPC, CyberStorm MK3 and Blizzard PPC). Not sure if Blizzard 1230, 1240 and 1260 SCSI-Kit had this possibility. IIRC, not.
