PCI BIOS and interrupts

Symptom:

Cause:

All these symptoms indicate that there is a conflict in the hardware resources. These resources are in particular interrupts (IRQ), port addresses, DMA channels and memory mapped I/O areas.

The conflicts appear when e.g. two plug-in boards use the same interrupt or write to the same port address. Or when the I/O area is used by other components.

Due to this, the computer cannot reach clearly the single components anymore or the signals for one component are wrongly interpretated by the others (logically).

Solution:

Partially with EISA and PCI systems (many other older ones), the interrupts must however be jumpered on the board for every hardware.
