3.4.2.4 

Serialized IRQ Support 

The Intel® Server Board SE7520AF2 supports a serialized interrupt delivery mechanism. 
Serialized Interrupt Requests (SERIRQ) consists of a start frame, a minimum of 17 IRQ / data 
channels, and a stop frame. Any slave device in the quiet mode may initiate the start frame. 
While in continuous mode, the start frame is initiated by the host controller. 

3.4.2.5 

IRQ Scan for PCIIRQ 

The IRQ / data frame structure includes the ability to handle up to 32 sampling channels with 
the standard implementation using the minimum 17 sampling channels. The Intel® Server 
Board SE7520AF2 has an external PCI interrupt serializer for PCIIRQ scan mechanism of 
ICH5-R to support 16 PCIIRQs.
