Intel Desktop Board D845PEBT2 Technical Product Specification 3.2 BIOS Flash Memory Organization The Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory device. Internally, the device is grouped into eight 64-KB blocks that are individually erasable, lockable, and unlockable. 3.3 PCI Autoconfiguration The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card. Autoconfiguration information is stored in ESCD format. For information about The versions of PCI and Plug and Play supported by the BIOS Refer to Section 1.4, page 17 3.4 System Management BIOS (SMBIOS) 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 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.

3.2 BIOS Flash Memory Organization
The Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory device.
Internally, the device is grouped into eight 64-KB blocks that are individually erasable, lockable,
and unlockable.
3.3 PCI Autoconfiguration
The BIOS can automatically configure PCI devices.
PCI devices may be onboard or add-in cards.
Autoconfiguration lets a user insert or remove PCI cards without having to configure the system.
When a user turns on the system after adding a PCI card, the BIOS automatically configures
interrupts, the I/O space, and other system resources.
Any interrupts set to Available in Setup are
considered to be available for use by the add-in card.
Autoconfiguration information is stored in
ESCD format.

3.4 System Management BIOS (SMBIOS)
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 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.
