I have an internal zip drive that is not working Win95 on a particular board. The chipset on the board is Intel 82430 FX/VX/HX. The drive will show up in windows but not read or format zip disks. I've tried the zip drive on other systems and it works just fine. I've also tried two other zip drives with the same result. I've disable the PNP setting as Iomega suggests, same result.
