Intel S875WP1-E Fast Booting Systems with Intel Rapid BIOS Boot, Booting Without Attached Devices

Booting Without Attached Devices

For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present:

•Video adapter

•Keyboard

•Mouse

Fast Booting Systems with Intel® Rapid BIOS Boot

These factors affect system boot speed:

•Selecting and configuring peripherals properly

•Using an optimized BIOS, such as the Intel Rapid BIOS

Intel Rapid BIOS Boot

Using 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.

•Disable Quiet Boot, which eliminates display of the logo splash screen. This could save several seconds of painting complex graphic images and changing video modes.

•Enabled Intel® Rapid BIOS Boot. This feature bypasses memory count and the search for a diskette drive.

✏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).
