4. It is recommended that the BIOS always forward serial data to KT serial and expose
the KT device to OS. This enables the SOL functionality during boot.
The SPS Firmware Startup Guide provides details on configuring SOL.
SPS Firmware supports a large internal buffer within SOL that smoothes the LAN
and serial communication performance issues. The sizes of the buffer can be modi-
fied via PIA for optimum performance.
The SPS Firmware allows early reception and sending of serial data even before
POST.
This is done by communicating SOL status to the BIOS using a bit in the FW Status
Register which can in turn be read by the BIOS during boot to enable the console
redirection. This can be useful to send debug information for early integration.
Command example :
ipmitool –I lpanlus –H 192.168.1.1 –U USERID –P PASSW0RD sol activate
