NEC Solution Gear 2-Vr4131 Development Kit Hardware Restrictions and Limitations
Keep in mind the following NEC Solution Gear 2-Vr4131 Development Kit restrictions and limitations:
- The PCI INTC routed through the ALI M1535+ chip on the baseboard does not work properly. The PCI card using this interrupt will not work. This situation occurs only with a special card or when the PCI extension box is used, because the interrupt is not attached to the PCI INTA signal on a baseboard PCI slot.
