Accessing information from a firmware using two-dimensional barcodes

摘要

A firmware setup utility executing on a computing system is configured to display a two-dimensional barcode, such as a Quick Response (“QR”) code. The two-dimensional barcode may be encoded with data about the computing system and/or a hyperlink specifying a location from which additional information may be retrieved. Another device, such as a mobile device, may be utilized to scan the two-dimensional barcode, decode the information contained therein, and present the data. If a hyperlink is encoded in the two-dimensional barcode, the device may retrieve the additional information from the specified location and present the retrieved data.

1. A computer-implemented method for providing information in a firmware environment utilizing two-dimensional barcodes, the method comprising computer-implemented operations for:
displaying, by way of a computing system, one or more selectable headings in a user interface of a firmware setup utility; gathering from the computing system, for each of the one or more selectable headings, data associated with the computing system, the data providing additional information associated with the selectable heading; generating a two-dimensional barcode for each of the one or more selectable headings, the two-dimensional barcode encoding the gathered data; detecting a user input selecting one of the one or more selectable headings; determining whether the data associated with the computing system for the selected one of the one or more selectable headings comprises an error message related to a test failure; in response to determining that the data associated with the computing system does not comprise the error message, displaying, in the user interface, the two-dimensional barcode corresponding to the selected one of the one or more selectable headings in response to detecting the user input; and in response to determining that the data associated with the computing system comprises the error message, increasing a display size of the two-dimensional barcode encoding the error message beyond a display size of the two-dimensional barcode corresponding to the selected one of the one or more selectable headings.
