I have a zorro 4 card, when I plug it into my A1200 with no expansion I get a ROM error (Red screen)
Give the board and passthrough adapter a good look over for any solder bridges or other shorts,as the red screen can be caused by a something short circuiting any of the address lines (it can cause the ROM checksum not to match it's calculated value and so the startup code thinks the ROM is bad)
IIRC, there was someone else posting on here a while back with similar problems and posted a piccy showing some crap soldering that stopped it working properly
Edit :
Found the piccy
