Now when I took out the forst card and tried the Blizzard, one thing that scared me is when I popped the Blizzard in, I got some weird lines on the screen (akin those that flash sometimes on loading screens), and then the infamous software error...

I booted with both buttons, screen came up fine, booted into a floppy with sysinfo and all looked good too.


From memory booting with both buttons will have disabled the card.

The ram jumper may be set incorrectly

To start with you may want to set the jumpers to 0mb ram and kickstart in rom. I'm not sure if fpu clock will make a difference in booting, but setting it to synchronous might be worth doing.

If it still doesn't work then try removing the oscillator/fpu/ram, if that still doesn't work then there may be a problem with the card or your a1200.
