CPUCARD/S option is forceful, that is it will always assume the hw is there and that it works as expected. Thus, if the mapping fails for whatever reason, you get a reboot loop.
Anyway, why it fails? That's a good question. AFAIK there is no maprom jumper on the board, so it shouldn't be any unset jumper. I know some Phase5 boards required memory module on certain memory bank to be able to use maprom, maybe this is it? If not all banks are in use you could try different memory module combinations.
Other than that, I'm at loss. I personally ever only owned Blizzard 1230-III and Blizzard PPC boards, so I really can't help much here, and anyway my A1200 has retired now (writing this on my peg2).
Maybe someone with CS MK-I knows more? Maybe someone has managed to get BlizKick working right on it and could help?
Also when i try:
blizkick cpucard devs:kick1.3
the system reboots but freezes (monitor goes into standby)
KS 1.3 doesn't have 68040 CPU support in it, so it is easily possible that kick1.3 just nukes... It worked with my A1200 + B1230-III (68030) though.
