Platform Management Intel® Server Board X38ML Legacy Console Redirection: The BIOS enables Legacy operating system redirection on Serial A or Serial B, depending upon the BIOS settings. Legacy operating system redirection happens when the user sets the Baud, Flow Control, and Terminal Type. SOL Found Active: If SOL is found active, the BIOS overrides the BIOS settings and autoenables Legacy operating system redirection on the SOL console. 5.23.4 Wired For Management (WFM) Wired for Management is an industry initiative to increase overall manageability and reduce total cost of ownership. WFM allows a server to be managed over a network. The system BIOS supports the System Management BIOS Reference Specification, Version 2.5 to help higherlevel instrumentation software meet the Wired For Management Baseline Specification, Revision 2.0 requirements. 5.23.4.1 PXE BIOS Support The BIOS supports the EFI PXE implementation as specified in Chapter 15 of the Extensible Firmware Interface Reference Specification, Version 1.1. To use PXE, the EFI Simple Network Protocol driver and the UNDI driver for the installed network interface card must be loaded. The UNDI driver should be included with the network interface card. The Simple Network Protocol driver is available at http://developer.intel.com/technology/framework. The BIOS supports legacy PXE option ROMs in legacy mode and includes the necessary PXE ROMs in the BIOS image for the onboard controllers. The legacy PXE ROM is required to boot a non-EFI operating system over the network. 5.23.5 System Management BIOS (SMBIOS) The BIOS provides support for the System Management BIOS Reference Specification, Version 2.5, to create a standardized interface for manageable attributes that are expected to be supported by DMI-enabled computer systems. The BIOS provides this interface via data structures through which the system attributes are reported. Using SMBIOS, a system administrator can obtain the types, capabilities, operational status, installation date, and other information about the server components. Refer to the SMBIOS structure tables in BIOS EPS about the access methods. 5.23.6 Security The BIOS uses passwords to prevent unauthorized tampering with the server configuration. The BIOS supports both user and administrator passwords. An administrator password must be entered before a user password can be selected. The maximum length of the password is seven characters. The password must be alphanumeric (a-z, A-Z, 0-9). It is not case-sensitive. You can clear a password by changing it to a null string. Entering the user password allows the user to modify the time, date, and user password. Other setup fields can be modified only if the administrator password is entered. If only one password is set, the password is required to enter BIOS Setup. 88 Revision 1.3 Intel order number E15331-006

Intel® Server Board X38ML

Revision 1.3

Intel order number E15331-006

Legacy Console Redirection:

The BIOS enables Legacy operating system redirection on Serial A or Serial B, depending upon

the BIOS settings. Legacy operating system redirection happens when the user sets the Baud,

Flow Control, and Terminal Type.

SOL Found Active:

If SOL is found active, the BIOS overrides the BIOS settings and auto-

enables Legacy operating system redirection on the SOL console.

5.23.4

Wired For Management (WFM)

Wired for Management is an industry initiative to increase overall manageability and reduce total

cost of ownership. WFM allows a server to be managed over a network. The system BIOS

supports the

System Management BIOS Reference

Specification, Version 2.5 to help higher-

level instrumentation software meet the

Wired For Management Baseline Specification

Revision 2.0 requirements.

5.23.4.1

PXE BIOS Support

The BIOS supports the EFI PXE implementation as specified in Chapter 15 of the

Extensible

Firmware Interface Reference Specification

, Version 1.1. To use PXE, the EFI Simple Network

Protocol driver and the UNDI driver for the installed network interface card must be loaded. The

UNDI driver should be included with the network interface card. The Simple Network Protocol

driver is available at

http://developer.intel.com/technology/framework

The BIOS supports legacy PXE option ROMs in legacy mode and includes the necessary PXE

ROMs in the BIOS image for the onboard controllers. The legacy PXE ROM is required to boot

a non-EFI operating system over the network.

5.23.5

System Management BIOS (SMBIOS)

The BIOS provides support for the

System Management BIOS Reference

Specification, Version

2.5, to create a standardized interface for manageable attributes that are expected to be

supported by DMI-enabled computer systems. The BIOS provides this interface via data

structures through which the system attributes are reported. Using SMBIOS, a system

administrator can obtain the types, capabilities, operational status, installation date, and other

information about the server components.

Refer to the SMBIOS structure tables in BIOS EPS about the access methods.

5.23.6

Security

The BIOS uses passwords to prevent unauthorized tampering with the server configuration. The

BIOS supports both user and administrator passwords. An administrator password must be

entered before a user password can be selected. The maximum length of the password is

seven characters. The password must be alphanumeric (a-z, A-Z, 0-9). It is not case-sensitive.

You can clear a password by changing it to a null string. Entering the user password allows the

user to modify the time, date, and user password. Other setup fields can be modified only if the

administrator password is entered. If only one password is set, the password is required to enter

BIOS Setup.
