3 Desktop Management ✎ Support for specific features described in this guide may vary by model or software version. 3.1 Initial Configuration and Deployment HP computers come with a preinstalled system software image. After a brief software “unbundling” process, the computer is ready to be used. A customized software image may be deployed by: ■ Installing additional software applications after unbundling the preinstalled software image.
Desktop Management 1. Remove all removable media and turn off the power. 2. Insert a diskette, CD, or USB flash device containing the desired BIOS image file in the root directory. The media must be formatted using the FAT12, FAT16, or FAT32 file system. 3. Turn on power to the system. If no appropriate BIOS image file is found, the failsafe Boot Block BIOS will attempt to start the system from a bootable device.
Desktop Management 3.2.4 World Wide Web Site When making the transition to new or revised operating systems, it is important to implement the support software designed for that operating system. If you plan to run a version of Microsoft Windows that is different from the version included with your computer, you must install corresponding device drivers and utilities to ensure that all features are supported and functioning properly.
Desktop Management 1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart. 2. As soon as the computer is turned on, press and hold the F10 key until you enter Computer Setup. Press Enter to bypass the title screen, if necessary. you do not press the F10 key at the appropriate time, you must turn the computer off, then on ✎ Ifagain, and press the F10 key again to access the utility.
