Note: Sector erase by SW is not supported. In order to delete a sector, the serial (bit bang) interface
should be used.
3.2.4.3 FLASH Device Information
While Intel does not make specific recommendations regarding FLASH devices, the
following devices have been used successfully in previous designs:
3.3 SMBus and NC-SI
SMB and NC-SI are optional interfaces for pass-through and/or configuration traffic
between the BMC and the 82575 Ethernet Controller. Please refer to the 82575 TCO/
System Management Interface Guide for more information
.
Note: Intel recommends that the SMBus be connected to the ICH or BMC for the EEPROM
recovery solution. If the connection is to a BMC, it will be able to send the EEPROM
release command.
The 82575 Ethernet Controller NC-SI interface is a connection to an external BMC. It
operates in one of two modes:
• NC-SI-SMB mode - In conjunction with an SMB interface, where pass-through
traffic passes through NC-SI and configuration traffic passes through SMB
• NC-SI mode - As a single interface with an external BMC, where all traffic (other
than header redirection) between the 82575 Ethernet Controller and the BMC flows
through the interface.
The Clock-out (if enabled) is provided in all power states (unless the device is
disabled).
