SYMPTOMS

CardBus cards may not work on computer with a Vesuvius chip set.

CAUSE

The Vesuvius PCI IRQ miniport driver (Pcimp.pci) does not support the SetTrigger and GetTrigger functions that report and set level-triggered interrupts. In order for the CardBus bridge to be configured for a CardBus card's memory and I/O windows, CardBus cards require level-triggered interrupts.

  1. Click Start, point to Settings, click Control Panel, and then double- click the System icon.
  2. Click the Device Manager tab.
  3. Double-click the System Devices branch to expand it.
  4. Double-click PCI Bus, and then click the IRQ Steering tab.
  5. Click the Use IRQ Settings check box to clear it, click OK, and then click OK.
  6. Restart your computer.

STATUS

This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows.
