Interrupts
The CP6500-V board uses the standard AT IRQ routing (8259 controller).
This interrupt routing is the default, but can be modified via the BIOS.

Warning!
IRQ5 should normally have only
one
source enabled, otherwise improper
system operation may result.
If more than one source is required to be enabled, contact Kontron Modu-
lar Computers’ Technical Support before implementing the IRQs.
For events that are not time critical, such as ENUM, DERATE, etc., polling
should be considered instead of using an IRQ.
