Yes, it came with memory installed (4x - all banks filled). I just didn't know the ram size of each. I just assumed they were 1MB (no size labels on them) each because the jumper was not present, usually indicating 4MBs. I started it up and everything sounded normal, but I received the jail bar screen.

Okay, I will install only 2x modules in Bank A as you instructed and see what happens... thank you very much for your instructions and sharing your knowledge...
