Page 87: Overview Of Bios Features
3.10 BIOS Security Features....................94 3.1 Introduction The D845HV and D845WN boards use an Intel/AMI BIOS that is stored in the Firmware Hub (FWH) and can be updated using a disk-based program. The FWH contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. -
Page 88: Bios Flash Memory Organization
Intel Desktop Board D845HV/D845WN Technical Product Specification 3.2 BIOS Flash Memory Organization The Intel 82802AB 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. -

Play operating system can obtain the SMBIOS information. For information about Refer to The D845HV and D845WN boards’ compliance level with SMBIOS Section 1.4, page 17 3.5 Legacy USB Support Legacy USB support enables USB devices such as keyboards, mice, and hubs to be used even when the operating system’s USB drivers are not yet available. -
Page 90: Bios Updates
Legacy USB support is for keyboards, mice, and hubs only. Other USB devices are not supported in legacy mode. 3.6 BIOS Updates The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: ®... -
Page 91: Language Support
During POST, an Intel splash screen is displayed by default. This splash screen can be replaced with a custom splash screen. A utility is available from Intel to assist with creating a custom splash screen. The custom splash screen can be programmed into the flash memory using the BIOS upgrade utility. -
Page 92: Boot Options
Intel Desktop Board D845HV/D845WN Technical Product Specification 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. -
Page 93: Intel Rapid Bios Boot
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. -
