Hi,
I've obtained a "Conner 2MB Floppy Controller" which is 8 bit ISA. It appears to have a BIOS chip on it and thus may support high density floppies on nonsupporting systems...yay?
That's not the question, however. It has a bank of jumpers, clearly labeled, but I need to know what to set them to. The card is being used in a typical XT clone mobo, no integrated features, but I am using a VGA graphics card.
The floppy card provides these options:
IO Address: 1, 2, 3, 4
IRQ: 3, 4, 5, 6, 7, 9
DMA: 1, 2, 3
Randomly guessing at these settings could take forever and the number of power cycles in quick succession to each other to accomplish that could damage the equipment. Can anyone offer a couple "highly likely to work" combinations for this setup? It does not seek either a 3.5" high density or 5.25" high density drive with no jumpers installed, and my random guess of 3/5/2 (IO, IRQ, DMA respectively) also didn't cause the drives to seek.
Thanks in advance!
