Purple screen of Death, Boing Bag 2

[punkyclown]

Hi, I just tried to update my A1200 with Boing Bag 2, 3.9.  I did push the button that asked if I wanted to update my rom.  Now when I start my Amiga I get a purple screen and nothing else.  I can still boot into 3.1 floppy.  Is there someway for me to back out of this?
Thanks.

Thanks for the help, this makes sense.  But I am loading Squirrel SCSI and it calls out the SetPatch in that upload.  I have fiddled with it a bit, but that seems to have worked!
Question, am I losing something by making this call?  Can't I just replace the file with a fresh one?  Thanks again!!
