4.1.12 LED Behavior During POST
After power up/reset and while BIOS runs the LEDs are used to signalize the power up/ BIOS
phases. The state of LEDs is defined so that in case of a hang, the LEDs clearly indicate in which
boot up phase the hang occurred. In general, to indicate that the POST is in progress, the BIOS
toggles the user LED for every POST task it executes. After the POST has been completed, the
BIOS switches off the LEDs. The LEDs marked with B1/U1,B2/U2 and U3 will be used for this
purpose.
