Just to let you all know I did indeed solve my cd boot problem on the A1200 with BlizzPPC SCSI. The ability to actually boot from CD (with no software intervention) seems to be only possible on an initial boot. By this I mean a power cycle (when you first switch on). This is the only time you will get CDO listed as a bootable device in the early start-up (both mouse buttons).
It is not listed when doing a reboot or 3 fingered salute.
It took a while but I got there in the end.
Good 'ol determination ;-) ;-) ;-)
