Desktop Board Features
USB 2.0 Support
The Desktop Board supports up to seven USB 2.0 ports (three ports routed to the back
panel and four ports routed to two front panel USB 2.0 headers). One of the front
panel USB headers supports an Intel Z-U130 USB Solid-State Drive (or compatible
device). The USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1
devices will function normally at USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support
USB 2.0 transfer rates. Disabling High-Speed USB in the BIOS reverts all USB 2.0
ports to USB 1.1 operation. This may be required to accommodate operating systems
that do not support USB 2.0.
NOTE
Computer systems that have an unshielded cable attached to a USB port might not
meet FCC Class B requirements, even if no device or a low-speed USB device is
attached to the cable. Use a shielded cable that meets the requirements for a
full-speed USB device.
Mass Storage Support
The board provides three ATA connectors that can be used to add storage capability to
the board. The following connectors are included:
• One PATA connector that supports two devices
• Two SATA connectors that support one device per connector
PATA Interface
The ICH7-M’s PATA controller has one bus-mastering PATA interface that is accessible
through a 44-pin connector that is compatible with 2.5 or 3.5 inch PATA hard drives
(including power support for 2.5 inch hard drives). The PATA interface supports the
following modes:
• Programmed I/O (PIO)
• 8237-style DMA
• Ultra DMA
• ATA-66
• ATA-100
NOTE
ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce
reflections, noise, and inductive coupling.
The PATA interface also supports ATAPI devices (such as CD-ROM drives) and ATA
devices using the transfer modes.
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector
(ECHS) translation modes. The drive reports the transfer rate and translation mode to
the BIOS.
19
Intel Desktop Board D945GSEJT Product Guide
SATA Interface
The Desktop Board supports two Serial ATA channels (3.0 Gb/s) that support one
device per channel. The SATA controller supports IDE and ACHI configuration and can
operate in both legacy and native modes.
Expandability
The Desktop Board provides the following expansion capability:
• One PCI connector. The connector can support either a single PCI add-in card or a
single- or dual-slot PCI riser card.
• One PCI Express Full-Mini Card slot.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI
and IDE auto-configuration utilities, and the video BIOS.
ATA Auto Configuration
If you install an ATA device (such as a hard drive) in your computer, the autoconfiguration utility in the BIOS automatically detects and configures the device for
your computer. You do not need to run the BIOS Setup program after installing an
ATA device. You can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.
PCI/PCI Express Auto Configuration
If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express
auto-configuration utility in the BIOS automatically detects and configures the
resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need
to run the BIOS Setup program after you install a PCI/PCI Express add-in card.
20
Desktop Board Features
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the supervisor or user
password was entered.
• Setting a user password restricts who can boot the computer. The password
prompt is displayed before the computer is booted. If only the supervisor
password is set, the computer boots without asking for a password. If both
passwords are set, you can enter either password to boot the computer.
For instructions on resetting the password, see Clearing Passwords on page 48.

Hardware Support
Fan Header
The Desktop Board has a 3-pin chassis fan header. See Figure 15 on page 46 for the
location of the chassis fan header.
+5 V Standby Power Indicator LED
CAUTION
If the AC power has been switched off and the standby power indicator is still lit,
disconnect the power cord before installing or removing any devices connected to the
board. Failure to do so could damage the board and any attached devices.
The Desktop Board’s standby power indicator, shown in Figure 3, is lit when there is
standby power to the system. This includes the DIMM socket and the PCI bus
connector, even though the computer appears to be off.
