Platform Management Intel® Server Board X38ML 5.23.1 IPMI Intelligent platform management refers to autonomous monitoring and recovery features that are implemented in the platform hardware and firmware. Platform management functions such as inventory, the event log, monitoring, and system health reporting are available without help from the host processors and when the server is in a powered down state, as long as AC power is attached. The baseboard management controller (BMC) and other controllers perform these tasks independently of the host processor. The BIOS interacts with the platform management controllers through standard interfaces. The BIOS enables the system interface to the BMC in early POST. The BIOS logs system events and POST error codes during the system operation. The BIOS logs a boot event to BMC early in POST. The events logged by the BIOS follow the Intelligent Platform Management Interface Specification, Version 2.0. IPMI defines the required use of all but two bytes in each event log entry called Event Data 2 and Event Data 3. An event generator can specify that these bytes contain OEM-specified values. The contents of these bytes are defined in Section 6.2. 5.23.2 Console Redirection The BIOS supports redirection of both video and keyboard through a serial link (serial port). When console redirection is enabled, the local (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. You can also control the system from a remote console, so a host keyboard or monitor is not required. Utilities that can be executed remotely include BIOS Setup. 5.23.2.1 Serial Configuration Settings For optimal configuration of Serial Over LAN or EMP, refer to the BMC EPS. 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. 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. 5.23.2.2 Keystroke Mappings 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 communication program. The keystroke mappings follow VT-UTF8 format with the following extensions. 5.23.2.2.1 Standalone Key for Headless Operation The Microsoft Headless Design Guidelines describes a specific implementation for the key as a single standalone keystroke: 84 Revision 1.3 Intel order number E15331-006

5.23.1

IPMI

Intelligent platform management refers to autonomous monitoring and recovery features that

are implemented in the platform hardware and firmware. Platform management functions such

as inventory, the event log, monitoring, and system health reporting are available without help

from the host processors and when the server is in a powered down state, as long as AC power

is attached. The baseboard management controller (BMC) and other controllers perform these

tasks independently of the host processor. The BIOS interacts with the platform management

controllers through standard interfaces.

The BIOS enables the system interface to the BMC in early POST. The BIOS logs system

events and POST error codes during the system operation. The BIOS logs a boot event to BMC

early in POST. The events logged by the BIOS follow the

Intelligent Platform Management

Interface Specification

, Version 2.0.

IPMI defines the required use of all but two bytes in each event log entry called Event Data 2

and Event Data 3. An event generator can specify that these bytes contain OEM-specified

values. The contents of these bytes are defined in Section 6.2.

5.23.2

Console Redirection

The BIOS supports redirection of both video and keyboard through a serial link (serial port).

When console redirection is enabled, the local (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.

You can also control the system from a remote console, so a host keyboard or monitor is not

required. Utilities that can be executed remotely include BIOS Setup.

5.23.2.1

Serial Configuration Settings

For optimal configuration of Serial Over LAN or EMP, refer to the BMC EPS.

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.

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.

5.23.2.2

Keystroke Mappings

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 communication

program. The keystroke mappings follow VT-UTF8 format with the following extensions.

key as a single standalone keystroke:
