Platform Management Architecture

5. Platform Management Architecture
The BIOS supports many standards -based server management features and several
proprietary features.
5.1

Console Redirection

The BIOS supports redirection of both video and keyboard via a serial link (COM port). When
console redirection is enabled, the local (host server) keyboard input and POST 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 can run entirely via the remote console, including BIOS Setup.
5.1.1

Serial Configuration Settings

Both EMP and console redirection require N, 8, 1 mode (no parity, 8-bit data, 1 stop bit).
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 can receive the
redirected text.
Console redirection ends at the beginning of the legacy operating system boot (INT 19h). The
operating system is responsible for continuing the redirection from that point .
5.1.2

Keystroke Mappings

During console redirection, the remote terminal sends keystrokes to the local server. The
remote terminal may be a dumb terminal with a direct connection running a communication
program. The keystroke mappings follow VT -UTF8 format with the following extensions.
5.1.2.1 Setup Alias Keys
The <Del> and <Ctrl>-function key combinations are synonyms for the <F2> or "Setup" key.
They are implemented and documented, but are not to be prompted for in screen messages.
These hot keys are defined for co nsole redirection support, and are not to be implemented for
locally attached keyboards.
5.1.2.2 Standalone <Esc> Key for Headless Operation
The Microsoft Headless Design Guidelines describes a specific implementation for the <Esc>
key as a single standalone keyst roke:
<Esc> followed by a two-second pause must be interpreted as a single escape.
<Esc> followed within two seconds by one or more characters that do not form a
sequence described in this specification must be interpreted as <Esc> plus the
character or characters, not as an escape sequence.
