DOS PCI and Interrupts
I am developing a DOS based PCI device driver for a communications card. I
am a little confused as to how to handle the interrupt. Since PCI interrupts
may be shared, how do I get my ISR to work properly?
Do I need to chain the interrupt?
Since PCI interrupts are level triggered, how will I know if there is
another device driver for a different device that is also sharing the
Any help will be greatly appreciated.
