3.9Adjusting Boot Speed

These factors affect system boot speed:

Selecting and configuring peripherals properly

Optimized BIOS boot parameters

3.9.1Peripheral Selection and Configuration

The following techniques help improve system boot speed:

Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays.

Select a CD-ROM drive with a fast initialization rate. This rate can influence POST execution time.

Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode changes in POST. These features may add time to the boot process.

Try different monitors. Some monitors initialize and communicate with the BIOS more quickly, which enables the system to boot more quickly.

3.9.2BIOS Boot Optimizations

Use of the following BIOS Setup program settings reduces the POST execution time.

In the Boot Menu, set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time.

In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can reduce up to four seconds of option ROM boot time.

NOTE

It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen.

This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup program).

D945GCLF2 specifications

The Intel D945GCLF2 is a compact and efficient motherboard designed for the Intel Atom processor family, particularly suited for low-power, cost-sensitive systems. This mini-ITX form factor board was released as a part of Intel's D945 series, targeting small form factor PCs, embedded systems, and home theater PC (HTPC) builds.

One of the standout features of the D945GCLF2 is its support for the Intel Atom N270 processor, a dual-core CPU that operates at a low thermal design power (TDP) of just 4 watts. This makes the board ideal for users looking to build energy-efficient systems without compromising on performance. The motherboard supports up to 2GB of DDR2 RAM, utilizing a single-channel memory architecture, which, while modest by today’s standards, suffices for basic computing tasks such as browsing, document editing, and media playback.

In terms of connectivity, the D945GCLF2 integrates a variety of I/O ports that enhance usability. It features four USB 2.0 ports, one PCI slot, and an IDE connector, catering to older peripherals while also allowing for the installation of additional components like graphics cards and network adapters. The onboard Intel Graphics Media Accelerator 950 provides adequate graphics performance for everyday activities and even supports HD video playback, making it a solid choice for multimedia applications.

Incorporating Intel's Advanced Configuration and Power Interface (ACPI) technology, the D945GCLF2 allows for efficient power management, giving users the flexibility to optimize their system's energy consumption. The board also includes essential connectivity options such as Ethernet through a 10/100 LAN port, facilitating wired networking capabilities.

Furthermore, the D945GCLF2 is equipped with multiple storage options; it provides support for Serial ATA (SATA) devices, allowing for faster data transfer rates compared to traditional PATA drives. The BIOS is user-friendly and offers a range of settings for users looking to tweak their system's performance.

Overall, the Intel D945GCLF2 motherboard is a robust solution for anyone looking to build a low-cost, low-power computing system. Its combination of small form factor, energy efficiency, and decent performance makes it suitable for a variety of applications, from basic user tasks to serving as the core of a compact home theater setup. Despite its age, the D945GCLF2 remains relevant for specific, budget-friendly builds, showcasing Intel's legacy in innovative motherboard design.
