2.3 Server Management
The BIOS supports many standard-based server management features and several propri-
etary features. The Intelligent Platform Management Interface (IPMI) is an industry stan-
dard and defines standardized, abstracted interfaces to platform management hardware.
The BIOS implements many proprietary features that are allowed by the IPMI specification,
but these features are outside the scope of the IPMI specification. This section describes
the implementation of the standard and proprietary features.
Console Redirection
The BIOS supports redirection of both video and keyboard via a serial link (serial port).
When console redirection is enabled, the local, or host server, keyboard input and video
output are passed both to the local keyboard and video connections, and to the remote
console through the serial link. Keyboard inputs from both sources are considered valid
and video is displayed to both outputs.
As an option, the system can be operated without a host keyboard or monitor attached to
the system and run entirely via the remote console. Utilities that can be executed remotely
include BIOS Setup.
Serial Configuration Settings
The BIOS does not require that the splash logo be turned off for console redirection to
function. The BIOS supports multiple consoles, some of which are in graphics mode and
some in text mode. The graphics consoles can display the logo and the text consoles
receive the redirected text.
Keystroke Mapping
During console redirection, the remote terminal sends keystrokes to the local server. The
remote terminal can be a dumb terminal with a direct connection and running a commu-
nication program. The keystroke mapping follows VT-UTF8 format with the following
extensions.
