Hi, I am having trouble only with the floppy controller on a UMC IDE card. Chipset=UM82C863F. This card is also runnung the CD, HD, and a serial mouse fine. I have swapped ribbon cables, and floppy drives to no avail. The back of the card lists MDC=1F0/179. What does MDC stand for. The Harddrive controller is set for Input/Output 01F0-01F7, 03F6-03F6. When I add new hardware it says the Floopy Controller has a conflict and disables it, but lists no conflict in the conflict box. Please help. Thanks. This problem is on a 486 Running Win95.
