BIOS upgrade kit contains documentation which describes in detail how to upgrade the
BIOS.
Update tool for Linux is provided with Basic Blade Services (BBS).
The BIOS can also be upgraded via IPMI - HPM.1 (Hardware Platform Management IPM
Controller Firmware Upgrade). Refer to
Firmware Upgrade .
4.14 BIOS Status Codes
The following tables list the BIOS POST codes. The BIOS POST codes are written to the blade's
I/O Port 80 register and can be obtained by reading the "POST code" on-board IPMI sensor. The
reading of the "POST code" sensor is only valid when the board is in the BIOS phase. The reading
can be used to locate the cause of a board hang during BIOS phase. When the board has booted
a OS, the reading of the '"POST code" sensor returns no valid status code.
For debugging purpose, the POST Codes can be printed to the serial console by setting DIP
Switch 4-3 and 4-4 to ON.
After performing a BIOS upgrade or after restoring a corrupted BIOS image, all BIOS settings
are reset to their default values except for parameters that are stored in IPMC storage area.
See
Table "System Boot Options Parameter #100 - Supported Parameters" on page 218 .
