3.Reboot the system into the updated page 1 BIOS.

See Section 2.3.12, “Resetting the Netra CP3250 Blade Server” on page 2-34.

5.9Power-On Self-Test

The system provides a rudimentary power-on self-test (POST) that runs each time the blade server boots to check the basic devices required for the system to operate.

The progress of the self-test is indicated by a series of POST codes. These codes appear at the bottom right corner of the system’s VGA screen (once the self-test has progressed far enough to initialize the video monitor).

You can configure the level of POST testing and some POST display features through the BIOS menus. For more information, see Section 5.10, “Changing POST Options” on page 5-9.
