Handling PCI interrupts in DOS

** Proprietary **
** High Priority **

Hello all,

I am developing a DOS based driver for the PCI card with interrupts.
The driver is not abel to detect the PCI interrupt.

Note : The PCI core once asserts INTAn, keeps asserted till the ISR clears its Interrupt status register in the memory space.

Is there any specific configuration that has to be done for the PIC or any other device on the MotherBoard?

Thanks,
