IPMI/KCS
INT Sel
Default setup of the IPMI/KCS Interrupt Pin. The value is loaded to the
Interrupt Pin register in the PCI configuration space. Default value in INT
D.
00b = INT A.
01b = INT B.
10b = INT C.
11b = INT D.

Reserved. Set to 1b.
4:0

Reserved. Set to 10000b.
a.
SOL enable over PCI (bit 14) and over LPC are
mutually exclusive
. As a result, only one should be enabled
in the EEPROM.

15:8
LAN D0a
Power
The value in this field is reflected in the PCI Power Management Data
Register of the LAN functions for D0a power consumption and dissipation
(
Data_Select
= 0 or 4). Power is defined in 100 mW units. The power
includes also the external logic required for the LAN function.
7:5
Function 0
Common
Power
The value in this field is reflected in the PCI Power Management Data
Register of function 0 when the
Data_Select
field is set to 8 (common
function). The most significant bits in the Data Register that reflects the
power values are padded with zeros.
4:0
LAN D3
Power
The value in this field is reflected in the PCI Power Management Data
Register of the LAN functions for D3 power consumption and dissipation
(
Data_Select
= 3 or 7). Power is defined in 100 mW units. The power
includes also the external logic required for the LAN function. The most
significant bits in the Data Register that reflects the power values are
padded with zeros.
