I accidentally I typed 0A to the Hex question of the Slot of the update and the Card updated to 2.1rc2 !!!! The program crashes on Quadra but if you press SHIFT during loading it runs and asks for the hex number of the NUBUS SLOT you have installed the Card.

TATTLETECH approve that the card updated to the new BIOS 2.1rc2 !!!

I will let you know later ... If it can see the hard disk (18GB IBM 68pin) and boot ...
