Docking PCIRQ3# Interrupt Assignment Register
Default = 04h
Reserved
Using OPTi IRQ driveback mechanism:
Docking PCIRQ3# Interrupt Assignment (PCIRQ3# Default) - Interrupts from the dock-
ing PCIRQ3# pin are mapped to this interrupt. Note that if an IRQ (an edge-mode inter-
rupt) is selected, this IRQ must be programmed to Level mode on the host chipset.
Level Mode:
00000 = Disabled
00010 = PCIRQ1#
00001 = PCIRQ0#
00011 = PCIRQ2#
Edge Mode: (Viper-N+)
10000 = IRQ0
10110 = IRQ6
10001 = IRQ1
10111 = IRQ7
10010 = IRQ2
11000 = IRQ8
10011 = IRQ3
11001 = IRQ9
10100 = IRQ4
11010 = IRQ10

Using Host PCI INTA#-D# (PCICFG 50h[6]=1)
000 = Disabled
001 = INTA#

Using OPTi IRQ driveback mechanism:
Docking Detect Interrupt Assignment - If attachment of a docking station is detected, or
if the device attached could not be determined, this interrupt will be generated. This
same interrupt will be generated when the docking station is removed.
Level Mode:
00000 = Disabled

00001 = PCIRQ0# (Default)
00101 = ACPI0
