I'm doing custom-build, and several of the motherboards I'm considering either do not have PS/2 connectors, or only have one. As certain legacy Linux distros will be used, I need two PS/2 connectors to avoid problems. Been looking for PCI or PCIe expansion cards to add-in these connectors, but Google is not cooperating...it only gives me serial port and parallel port cards. Anyone know of specific expansion card to add two PS/2 connectors (that picky Linux will accept)?
