Setting Interrupts 2-27
2.4 Setting Interrupts
You should not normally have to change the default interrupt routing for
the SYM22801, since performance is usually increased by having two
separate interrupts. However, if your system does not support two
separate interrupts, jumper TP9 (see Figure A.1) is provided to change
the interrupt routing. The following table explains the jumper settings:
Table 2.2 Setting Interrupts
Jumper
Setting Condition
Jumper Out
(default) INTB/ is routed to INTB/ on the PCI bus
Jumper In INTB/ is rerouted at power up to INTA/ on the
PCI bus
