Your computer seems to have trouble with the romupdate.

Boot off a floppy or without startup-sequence from the early startup-menu.

Rename "AmigaOS ROM Update" into something else and it should work again. It's in the DEVS: drawer.

You could also edit your startup-sequence and add noromupdate after QUIET.

I'm not sure if both programs are required. That also depends on the card you use. It could be that your card doesn't need it, check this site:

I also seem to recall that Blizkick has an optional module for cardpatch/reset. Don't know for sure though...
