Bridge Link (CN4)

The Bridge Link connector allows devices that requires Legacy/ISA interrupts to interface with the cpuModule. When ISA devices are installed in the system (via a PCI to ISA bridge card), the Bridge Link connector provides Legacy/ISA DMA request signals, as well as a serial interrupt signal which permits access to all available system interrupts.

Multiple devices may utilize the serial interrupt signal, SERIRQ, which is decoded on the cpuModule. Only one device may use the DMA request and grant signal pair.

Table 34 Bridge Link (CN4)

Pin	Signal	Function

1	GND	Ground

2	DMAREQ	Legacy/ISA DMA Request

3	SERIRQ	Serial Interrupt Request

4	DMAGNT	Legacy/ISA DMA Grant

Facing the connector pins, the pinout is:

SERIRQ

GND

DMAGNT

DMAREQ
