| 304 | This variable specifies the number of PIRQ interrupt links which are |
| 305 | routable. On most chipsets, this is 4, INTA through INTD. Some |
| 306 | chipsets offer more than four links, commonly up to INTH. They may |
| 307 | also have a separate link for ATA or IOAPIC interrupts. When the PIRQ |
| 308 | table specifies links greater than 4, pirq_route_irqs will not |
| 309 | function properly, unless this variable is correctly set. |
