In the 486 motherboard of my PC there are two cards: one for the drives and the other for the monitor.
I also got the third card which is supposed for the motherboard as well. However, when I inserted it to the slot of the motherboard, the monitor is black when swich on the PC. Can you tell me what is the card and how to use it?

P/N:55V531000A FCC ID:HNG920 CXRBBS2TLAI
On the biggest chip of the card:
On another chip:
