booting

boot

A boot causes the computer to start executing instructions. PCs and Macs contain built-in instructions in a ROM or flash memory chip that are automatically executed on startup. These instructions search for the operating system, load it and pass control to it. Booting a computer today means turning it on or selecting Restart. In the early days of computing, booting required pressing several buttons at the console.

Put Your Boots On!
The term comes from "bootstrap." Since bootstraps help you get your boots on, booting the computer helps it get its first instructions. The term is often used erroneously for application software. For example, you might hear someone say "let's boot Excel," whereas the correct usage is "launch Excel" or "load Excel." See cold boot, warm boot, clean boot, boot loader and first boot sequence.

Other features include an 866 MHz Intel Pentium III processor for high-performance operation, custom BIOS modifications that allow a rapid boot sequence, a front panel LCD that displays status messages useful for diagnostics and troubleshooting, and an optional redundant operation setup.
We solved this problem in the prototype by maintaining a boot sequence number on each client that is incremented when the client reboots.
The client configuration agent can run manually or it can be included in the image file, installed as part of the cloning process by the Imaging Software to run as a service following the boot sequence. This client configuration agent requires the use of a source file, which is placed on the hard drive by the imaging software during the imaging process.
