5.1.4 Board Information display
The BIOS displays the following board related information during the startup:
 System (Board) Name
 BIOS Version
 BIOS Build Date and Time
 Reset Type
 CPU Name
 Measured Frequency of the CPU
 Total Memory available for the CPU
 Glue Logic FPGA ID and Version
 Shared Memory Parameters if present
Most of the information is also displayed in the BIOS Setup Menu under "BIOS Information" and
"Platform Information".
5.2 BIOS Operation
5.2.1 POST
After power-up or reset, the BIOS performs a self-test, POST, which attempts to determine if
further operation is possible and that the detected configuration is expected. This process can
complete normally or result-in a warning or an error. The boot process does not stop after a
warning but displays a message on the primary display device. If an error is detected, the boot
process is halted. If possible, a message is displayed.
The POST process has checkpoints indicated by their status codes, which are output to the I/O
port 80h whose value is shown by the POST LED Display. The Glue Logic FPGA also supports a
possibility for the SPP to read out this value thus monitoring the BIOS' startup process.
In case of a CPU exception its code is also output to the I/O port 80h.
