Abstract
A method for assembling a computing device including initiating a board management controller of the computing device, the board management controller having at least one fuse, forming data to control a video display operatively connected to the computing device to show an image of a watermark, and modifying the computing device. The method also includes blowing the at least one fuse in response to modifying the computing device and adjusting the watermark in response to blowing the at least one fuse.
Claims18
A method for assembling a computing device, the method comprising:
- initiating a baseboard management controller of the computing device, the baseboard management controller having at least one fuse;
- forming data to control a video display operatively connected to the computing device to display an image of a watermark before blowing any of the at least one fuse, the watermark indicating whether an erroneous process or malicious process has occurred in the assembling of the computing device;
- modifying the computing device;
- blowing the at least one fuse in response to modifying the computing device;
- and
- adjusting the watermark to be displayed in response to blowing the at least one fuse.
A method for assembling a computing device, the method comprising:
- initiating a baseboard management controller of the computing device, wherein the baseboard management controller comprises a plurality of fuses, wherein a second fuse cannot be blown until a first fuse is blown, and wherein blowing of the plurality of fuses is for respective different phases of assembling the computing device;
- forming data to control a video display operatively connected to the computing device to display an image of a watermark;
- performing modifications of the computing device in the respective different phases in a given order;
- blowing the plurality of fuses in a specified sequence in response to performing the modifications of the computing device in the given order;
- and
- adjusting a display of the watermark in response to blowing the plurality of fuses in the specified sequence.
