Hi Icbrkr,
Goto Aminet and download, CardPatch.lha util/boot
what you describe is caused by the PCMCIA bugs present in the A1200.
I bought an 'Amiga compatible' card from Eyetech. I plugged it in and my A1200 would not boot. I removed the card, installed card patch, rebooted with card in place and it has worked since.
