Abstract

Disclosed is the display of a set of POST icons, each resembling a hardware device or subsystem, during the Power-On Self-Test (POST) procedure used for intializing and testing the hardware components and data areas of a computer system, to indicate the hardware component being tested.

Graphical Indicators of Power-on Self-Test Progression

      Disclosed is the display of a set of POST icons, each
resembling a hardware device or subsystem, during the Power-On
Self-Test (POST) procedure used for intializing and testing the
hardware components and data areas of a computer system, to indicate
the hardware component being tested.

      The Figure shows examples of icons created using simple
characters available in the IBM extended ASCII character set.  After
the video system is initialized and tested during the POST test,
these icons, or GPIs (Graphical Progression Indicators), may be
displayed as their respective components are tested.

      These indicators can be displayed with different screen
attributes to distinguish among four possible test phases: pre-test,
test, post-test pass, and post-test fail.  Standard attributes, such
as normal, intense, reversed, blinking, or color, may be used to
differentiate these phases.  The use of standard attributes results
in indications that work equally well on color and monochrome
monitors as well as on LCD and CRT displays.  For example, before the
POST communications port test begins, the indicator for the
communications port is displayed using a normal screen attribute.  As
this port is tested, the screen attribute of this indicator is
changed to intense.  If the communications port passes the test, this
screen attribute is returned to normal.  If the communications port
fails the test, this...
