82571EB/82572EI EEPROM Information Guide
13
Note:
The Management Enable Byte word 13h must be set to 000b (no manageability) when using the
ASF EEPROM image. It is the ASF agent’s responsibility to set this field to 001b for ASF mode.
If the additional PCI functions (SMS, IDE, COM) are enabled in the EEPROM, the firmware is
notified of their relevant functionality.
When no manageability mode is present or enabled and no other functionality is enabled (SMS,
IDE, COM), the manageability subsystem is not functional and the host interface is not functional.
In other words, it does not respond to accesses made to CSR addresses 8800h through 8FFFh.
The EEPROM contains information for the enabled mode only. Additional information on mode
operation (fail over enable, active port, etc.) is available in the manageability CSR area if the block
is functional.

Initialization Control 3 (Word 14h/24h, Lower Byte)
Note:
Word 14h is used for LAN 1. Word 24 is used for LAN 0.

No PHY
Reset for
IDE
No PHY reset when IDE or SOL is enabled. When asserted, this bit
can prevent the PHY reset signal according to the
MANC.BLK_PHY_RST value. This bit should be set to the same value
at both words (14h, 24h) to reflect the same option to both LANs.
0b = PHY reset always asserted by a PCIe* reset.
1b = PHY reset blocked by firmware.
