Intel PCI-X 27 IPv4 Address Words 15h 16h1 and 25h 26h, LED Configuration Defaults Word 2Fh2

EEPROM Interface

5.6.27IPv4 Address (Words 15h - 16h1 and 25h - 26h)

The following table lists the initial values for the IPv4 addresses.

Table 5-13. IPv4 Addresses

Bit	Name	Description
31:0	IPv4 Address	The initial value of IPv4 Address Table entry 0. (IP4AT[0]).
		Refer to the EEPROM Address Map listed in Table 5-2for an indication
		of how the bytes are stored.

Note: Since the 82546GB/EB is a dual-port device, the IPv4 Address in 15h-16h corresponds to LAN B, and the IPv4 Address in 25h-26h corresponds to LAN A.

5.6.28IPv6 Address (words 17h - 1Eh1 and 27h - 2Eh)

The following table lists the initial values for the IPv6 addresses.

Table 5-14. IPv6 Address

Bit	Name	Description
127:0	IPv6 Address	The initial value of IPv6 Address Table entry 0. (IP6AT[0])
		Refer to the EEPROM Address Map listed in Table 5-2for an indication
		of how the bytes are stored.

Note: Since the 82546GB/EB is a dual-port device, the IPv6 Address in 17h-1Eh corresponds to LAN B, and the IPv6 Address in 27h-2Eh corresponds to LAN A.

5.6.29LED Configuration Defaults (Word 2Fh)2

This EEPROM word specifies the hardware defaults for the LEDCTL register fields controlling the LED0/(LINK_UP#) and LED2/LINK100 output behaviors. Refer to Table 13-60for the LED Control bit descriptions and Table 13-61for the Mode Encodings.

Note: A value of 0602h is used to configure default hardware LED behavior equivalent to 82544-based Copper adapters (LED0/LINK_UP#, LED1/ACTIVITY# (blinking), LED2/LINK100#, and LED3/LINK1000#).

5.6.30Boot Agent Main Setup Options (Word 30h)

The boot agent software configuration is controlled by the EEPROM with the main setup options stored in word 30h. These options are those that can be changed by using the Control-S setup menu or by using the IBA Intel Boot Agent utility.

Note: The 82541ER does not support the Intel Boot Agent functionality.

1.Applicable to the 82546GB/EB only.

2.Not applicable to the 82544GC/EI.
