BMC Flash Memory Layout and Content
On IXB2850 boards, the BMC firmware resides in the BMC local flash memory. The
organization of the flash memory is shown in
sectors are described in the subsections that follow.
BMC flash memory organization
BMC Initial Loader
The first sector (128kB) of the BMC’s local flash is occupied by the BMC Initial Loader.
This is the first code executed by the BMC just after power is applied to the board. The
BMC Initial Loader is responsible for:
The BMC Initial Loader provides additional functionality for BMC image recovery. It
allows the loading of a new BMC image (using the Xmodem protocol) and the selection
of an operational image.
The functionality enables the updating of BMC images in the event that the software
does not operate correctly (that is, if it is not possible to load a new BMC image from
the BMC console or to select the alternate operational image).
The user can enter the BMC recovery boot loader by entering the three characters,
==2,
• Basic BMC initialization (EEPROM, flash, RAM)
• Selecting, loading and executing one of the BMC operational images
during the first four seconds of board startup.
