B/D/F/Type:
0/6/0/PCI
Address Offset:
34h
Default Value:
88h
Access:
RO
Size:
8 bits
The capabilities pointer provides the address offset to the location of the first entry in
this device's linked list of capabilities.
6.2.22
INTRLINE6 - Interrupt Line
B/D/F/Type:
0/6/0/PCI
Address Offset:
3Ch
Default Value:
00h
Access:
RW
Size:
8 bits
This register contains interrupt line routing information. The device itself does not use
this value, rather it is used by device drivers and operating systems to determine
priority and vector information.

Interrupt Connection (INTCON)
Used to communicate interrupt line routing information. BIOS
Requirement: POST software writes the routing information into
this register as it initializes and configures the system. The
value indicates to which input of the system interrupt controller
this device's interrupt pin is connected.
