Using The Boot Manager Program; Starting The Backup Server Firmware; Using The Integrated Management Module - IBM System x3550 M3 Type 4254 Problem Determination And Service Manual

Using the Boot Manager program

The Boot Manager program is a built-in, menu-driven configuration utility program
that you can use to temporarily redefine the first startup device without changing
settings in the Setup utility.
To use the Boot Manager program, complete the following steps:
1. Turn off the server.
2. Restart the server.
3. When the prompt <F12> Select Boot Device is displayed, press F12. If a
4. Use the Up arrow and Down arrow keys to select an item from the Boot
The next time the server starts, it returns to the startup sequence that is set in the
Setup utility.

Starting the backup server firmware

The system board contains a backup copy area for the server firmware (formerly
BIOS firmware). This is a secondary copy of the server firmware that you update
only during the process of updating the server firmware. If the primary copy of the
server firmware becomes damaged, use this backup copy.
To force the server to start from the backup copy of the server firmware, turn off the
server; then, place the J29 jumper in the backup position (pins 2 and 3).
Use the backup copy of the server firmware until the primary copy is restored. After
the primary copy is restored, turn off the server; then, move the J29 jumper back to
the primary position (pins 1 and 2).

Using the integrated management module

The integrated management module (IMM) is a second generation of the functions
that were formerly provided by the baseboard management controller hardware. It
combines service processor functions, video controller, and (when an optional
virtual media key is installed) remote presence function in a single chip.
The IMM supports the following basic system management features:
v Environmental monitor with fan speed control for temperature, voltages, fan
v Light path diagnostics LEDs indicators to report errors that occur with fans,
v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
v System event log (SEL).
v ROM-based IMM firmware flash updates.
v Auto Boot Failure Recovery (ABR).
v A virtual media key, which enables remote presence support (remote video,
