, for use later during OS set-up. For instance, a software driver may support several different plug-in cards and an adjustment to the configuration of the software driver may be required to handle interoperability between components. Upon completion of processing in the burn rack, the custom configured computer system is scanned for viruses, packaged, and shipped to the customer.
Once the computer system is shipped to the customer, if the OS and other applications are not pre-loaded at the time of manufacture of the computer system, the customer must load the OS and applications at the customer site. This process may take between twenty and forty-five minutes. The build-to-order manufacturing process described above, in which a computer system is shipped to the customer for initial set-up by the customer is referred to as the xe2x80x9cspray and prayxe2x80x9d manufacturing model. That is, the computer manufacturer sprays the bits down onto the hard disk drive and prays that when the customer performs the initial computer system set-up at the customer site, long after the manufacturer has touched the computer system, that the computer system initial set-up works well. The xe2x80x9cspray and prayxe2x80x9d model is problematic for several reasons. First, during the loading and initialization of the OS and applications by the customer at the customer site, it is not unusual for the customer to turn the system OFF and then ON again, believing that the inactivity of the computer system is an indication that the system is hung. If the computer is powered off during initial installation, the computer system configuration and initial set-up process may be severely affected. In this scenario, additional customer service is necessary and the OS may have to be reloaded by the computer manufacturer to place the system in its pre-shipment state so that the initial set-up process can begin again.
Another difficulty of the xe2x80x9cspray and prayxe2x80x9d model is that there is not a method for conclusively determining if the set-up will complete properly or has completed properly. There is no check of the hardware and software integrity of the completed system. With this model, the set-up is not complete until the computer system is at the customer site and undergoes the OS set-up. Because each custom built computer system includes a unique configuration, where the components can be different from one system to another, there was no readily available way to verify that

For instance, a software driver may confirm respective different plug - in card and an adaptation to the configuration of the software driver may be required to wield interoperability between part. Upon completion of processing in the burn rack, the custom configured calculator system is scanned for viruses, packaged, and ship to the customer. 
 Once the computer arrangement is shipped to the customer, if the OS and early applications are not pre - loaded at the time of fabrication of the computer system, the customer must load the oxygen and applications at the customer web site. This process may choose between twenty and forty - five minutes. The build - to - order fabrication process described above, in which a computer system is shipped to the customer for initial set - up by the customer is refer to as the xe2x80x9cspray and prayxe2x80x9d manufacturing model.

First, during the loading and initialization of the OS and applications by the customer at the customer web site, it is not unusual for the customer to turn the system OFF and then ON again, believing that the inactivity of the computer system is an reading that the arrangement is hung. If the computer is powered off during initial installation, the computer arrangement configuration and initial set - up process may be hard affected. In this scenario, additional customer service is necessary and the OS may consume to be reloaded by the computer manufacturer to place the system in its pre - shipment state so that the initial sic - up process can get down again. 
 Another difficulty of the xe2x80x9cspray and prayxe2x80x9d model is that there be not a method for conclusively determining if the hardening - up will dispatch properly or has completed properly. There be no check of the hardware and software integrity of the completed system. With this model, the set - up is not accomplished until the computer system is at the customer web site and undergoes the OS set - up. Because each custom built computer system includes a singular configuration, where the components can be different from one system to another, there was no readily available manner to control that
