Interrupt Usage Note
PCIC Control Net Cards require a PC Interrupt for use. You must have
at least 1 free interrupt before installing the PCIC board; otherwise
you will not be able to use the board.
There are only 15 Interrupts used on the PC architecture for devices.
Most ISA boards require exclusive use of interrupt(s) they are assigned.
Some newer PCI boards can share interrupts with other boards.
ATTENTION
!
Before Migration to R320.0, first verify your PC’s
Interrupt usage.
TIP
The interrupt must fall between 8 and 15. Once
defined, the board may share an interrupt with another
device.
