2-24 Installing the LSI21003
2.4 Setting Interrupts (Exceptional Cases)
Normally, you do not change the default interrupt routing for the
LSI21003, since performance is usually increased by having two
separate interrupts.
However, if your system does not support two separate interrupts, the
INTA/INTB/ jumper is provided to change the interrupt routing. This
capability requires enabling the INTA/INTB/ to act as a jumper for special
configuration purposes. This feature is not packaged with the standard
LSI21003, as the default interrupt routing is sufficient for most systems.
In the exceptional case, where a user would require jumper settings,
Table 2.2, “Setting Interrupts,” explains these settings:
Contact Technical Support for further information concerning jumper
settings for this board.

Jumper Setting Condition
Jumper Out (default) SCSI Channel B is routed to
INTB/onthePCIbus.
Jumper In SCSI Channel B is rerouted to
INTA/onthePCIbus.
