Read Progress Indicators from Last System Boot
Displays the boot progress indicators (check points), up to a maximum of 100,

are the progress indicators from the boot that produced the current sessions.
Below the dashed line are progress indicators from the boot preceding the one
that produced the current sessions.
The progress indication codes are chronological from bottom to top. The dashed

example of the POST error screen.
