I am using a MRI-PCIPP2 pci and I suspect it is something to do wit the Mode. It is supposed to be SPP/EPP/ECP compatable and auto selected.
OS is XP and up to date on Updates.
What I think is the problem is the PCI card is in the incorrect mode, but I have been unable to find any info on manually changing it.
Any help
