Overview of BIOS Features

This section details specific BIOS features for the KTQ45 board.

The KTQ45 board is based on the AMI BIOS core version 8.10 with Kontron BIOS extensions.

6.1

System Management BIOS (SMBIOS/DMI)

SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a

managed network.

The main component of SMBIOS is the Management Information Format (MIF) database, which contains

information about the computing system and its components. Using SMBIOS, a system administrator can

obtain the system types, capabilities, operational status, and installation dates for system components.

The MIF database defines the data and provides the method for accessing this information. The BIOS

enables applications such as third-party management software to use SMBIOS.

The BIOS stores and reports the following SMBIOS information:

• BIOS data, such as the BIOS revision level

• Fixed-system data, such as peripherals, serial numbers, and asset tags

• Resource data, such as memory size, cache size, and processor speed

• Dynamic data, such as event detection and error logging

Non-Plug and Play operating systems, such as Windows NT*, require an additional interface for obtaining

the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using

this support, an SMBIOS service-level application running on a non-Plug and Play operating system can

obtain the SMBIOS information.

6.2

Legacy USB Support

Legacy USB support enables USB devices such as keyboards, mice, and hubs to be used even when the

operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup

program, and to install an operating system that supports USB. By default, Legacy USB support is Enabled.

Legacy USB support operates as follows:

1. When you apply power to the computer, legacy support is disabled.

2. POST begins.

3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and

configure the BIOS Setup program and the maintenance menu.

4. POST completes.

5. The operating system loads. While the operating system is loading, USB keyboards and mice are

recognized and may be used to configure the operating system. (Keyboards and mice are not

recognized during this period if Legacy USB support is Disabled in the BIOS Setup.)

6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are

recognized by the operating system, and Legacy USB support from the BIOS is no longer used.

To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup

program is set to Enabled and follow the operating system’s installation instructions.

6.3

BIOS Update

The BIOS can be updated using Kontron utility called bf.exe, which are available on the Kontron Web site.

The utility supports DOS and Windows environment. Before updating the BIOS, AMT related restrictions

must be followed. Do not attempts to ignore below steps as it might result in corrupted BIOS.

Before updating the BIOS below steps must be followed:

Make sure that AMT technology is disabled under the menu: Advanced, Intel AMT Configuration,

Intel AMT Support.

Make sure not populate DIMM into SLOT 1 socket (DIMM socket closest to the CPU) The 3

remaining DIMM sockets can be freely used without restrictions.
