6.6 NVRAM Upgrade

In contrast to the BIOS image update, the setting update image is not directly written

to any of the BIOS SPI flashes. The BIOS settings are stored in the external SPI flash

of the IPMC to support a deferred activation. For extended flexibility the external SPI

flash supports different sections to store up to four BIOS setting images in the external

flash at the same time. Each of these settings can be set to “active” at any time and

will be copied to the active BIOS flash at the next OS boot.

6.6.1 Select Upgrade Section (optional)



As described above, the IPMC provides multiple upgrade sections for different

NVRAM sections. OEM commands are used to select the upload and activation

setting from the different BIOS setting sections in the external flash.
