Nomenclature
Specification Changes modifications current published specifications. These changes will incorporated next release specifications. Errata design defects errors. Characterized errata cause D820LP desktop board's behavior deviate from published specifications. Hardware software designed used with given Printed Board Assembly (PBA) BIOS revision level must assume that errata documented that BIOS revision level present desktop boards. Specification Clarifications describe specification greater detail further highlight specification's impact complex design situation. These clarifications will incorporated next release specifications. Documentation Changes include typos, errors, omissions from current published specifications. These changes will incorporated next release specifications.

Specification Changes listed this section apply D820LP Motherboard Technical Product Specification (Order Number A15751). Specification Changes will incorporated into future version that specification.
ADDITION FEATURE, FAST BOOTING SYSTEMS WITH INTEL® RAPID BIOS BOOT
Section 3.8, Overview BIOS Features will added. subsequent sections will renumbered accordingly:
Fast Booting Systems with Intel Rapid BIOS Boot
There three factors that affect system boot speed: Selecting configuring peripherals properly Using optimized BIOS, such Intel® Rapid BIOS Selecting compatible operating system BIOS configured default boot fastest possible speed. Empirical measurements have shown that some Intel® Desktop boards, when optimized described above, complete POST (Power Self Test) seconds less boot active Microsoft Windows* Millennium (Me) operating system seconds. addition appliance-like speed that benefits users, fast booting systems also increase OEM's manufacturing line throughput. 3.8.1 Peripheral Selection Configuration following techniques will help improve system boot speed: Choose hard drive with parameters, such "power-up data ready" less than eight seconds which will minimize hard drive startup delays. Western Digital Caviar series examples drives that meet this parameter. Select CD-ROM drive with fast initialization rate; variations influence POST times. Eliminate unnecessary features such video-company-logo displaying, screen repaints, mode changes. These time boot process. Plug Play communication between video BIOS monitor shows time variances. different monitors. Some monitors initialize more quickly, thereby enabling system boot more quickly.

3.8.2
Intel® Rapid BIOS Boot
There several BIOS settings, which adjusted, reduce execution time POST: hard disk drive first boot device. result, POST will seek diskette drive (saving about second from POST time) CD-ROM drive (saving about seconds). Disable Quiet Boot eliminate logo splash screen. This could save several seconds painting complex graphic images changing video modes. Make sure Intel® Rapid BIOS Boot option Boot menu BIOS Setup Program) enabled (this typically default setting). This feature bypasses memory count floppy seek. Disable feature (Preboot eXecutable Environment) will used. Doing reduce four seconds option boot time.

Monitors hard disk drives with minimum initialization times also contribute boot time that might fast that necessary logo screens POST messages cannot seen. this should occur, possible introduce programmable delay ranging from seconds (using Hard Disk PreDelay feature Advanced menu Configuration Submenu BIOS Setup Program).
