PCICFG 49h
Docking PCIRQ1# Interrupt Assignment Register
Default = 02h
Reserved
Using OPTi IRQ driveback mechanism:
Docking PCIRQ1# Interrupt Assignment (PCIRQ1# Default) - Interrupts from the dock-
ing PCIRQ1# 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# (Default)
00001 = PCIRQ0#
00011 = PCIRQ2#
Edge Mode: (Viper-N+)
10000 = IRQ0
10110 = IRQ6
10001 = IRQ1
10111 = IRQ7
10010 = IRQ2

10011 = IRQ3
11001 = IRQ9
10100 = IRQ4
11010 = IRQ10
10101 = IRQ5
Using Host PCI INTA#-D# (PCICFG 50h[6]=1)
000 = Disabled
001 = INTA#
010 = INTB# (default)
00100 = PCIRQ3#
00101-01111 = Rsrvd
11011 = IRQ11
