PCI Shared Interrupts v1.0 Shared interrupts are normal in PCI computers, but not all PCI device drivers support them. Although drivers for the Compaq controllers support shared interrupts, other PCI drivers used by your computer may not. If you're having problems with a shared interrupt, try one of the following: 1 Use your computer's BIOS setup program to change the interrupt assigned to this controller. 2 Make sure that your Compaq controller device driver loads AFTER the driver for any other device sharing this interrupt. 3 Contact the manufacturer of the other controller or add-in card that is sharing this interrupt for a new driver.
