5.1 About BIOS Settings

This section describes how to view and modify the BIOS settings.

The BIOS has a Setup utility stored in the BIOS flash memory. The Setup utility reports system information and can be used to configure the BIOS settings. The configured data is provided with context-sensitive help and is stored in the system's battery-backed CMOS RAM. If the configuration stored in the CMOS RAM is invalid, the BIOS settings will default to the original state specified at the factory.

5.1.1 Navigating BIOS Screens

The BIOS Setup utility contains menu screens; see Appendix A for illustrations of the screens.

Use the left and right arrow keys to move sequentially through the BIOS screens. Fields that can be reconfigured are displayed in color. All other fields are non-configurable. Use the up and down arrow keys to scroll through a screen's menu. Use the Tab key to move across columns.

5.1.2 BIOS Option ROMs

The Sun Netra CP3250 blade server has an option ROM for each of the following components:

Broadcom BCM 5715C base interfaces

Sun 10 GbE Multithreaded Networking Technolgy interfaces

Note - PXE boot from fabric interface (Sun 10GbE Multithreaded Networking Technology interfaces) is disabled by default. You must change the BIOS setting to boot from fabric interfaces.

5.6 Updating the BIOS

When they are updated, BIOS images will be available as patches at the following web site:

http://sunsolve.sun.com/

Use the Solaris BIOS Update Utility or the Linux BIOS Update Utility to implement the updates. For more information, see the Netra CT 900 Server Product Notes (819-1180).

5.7 Secondary BIOS Image

The Sun Netra CP3250 blade server provides dual 1-Mbyte BIOS chips that support redundant BIOS images for increased reliability. The default chip (page 0) acts as the primary BIOS chip and is automatically selected for update during a firmware upgrade. The secondary BIOS chip (page 1) retains the original BIOS image, and can be used through manual configuration in the unlikely case where the primary BIOS becomes corrupt.

If the primary BIOS becomes unbootable, use the secondary BIOS to manually boot the blade server:

1. Log into the Shelf Manager.

2. To select the secondary BIOS image, type:

 # clia sendcmd 96 2e 81 00 00 2a 01

For example:

 # clia sendcmd 96 2e 81 00 00 2a 01 <----- Setting the boot page to 1
 
 Pigeon Point Shelf Manager Command Line Interpreter
 
Completion code: 0x0 (0)   <----- successful completion code
Response data: 00 00 2A    <----- no data returned

3. To boot the blade server from the Shelf Manager, type:

 # clia activate board n

Note - Once the blade server is booted, reset the blade server to use the primary BIOS image (page 0).

5.8 Perform a Live Firmware Upgrade

To upgrade the BIOS firmware while retaining the current BIOS image, follow these steps:

1. Switch the BIOS image from page 0 to page 1.

See Section 5.7, Secondary BIOS Image.

2. Use the Solaris BIOS Update Utility to upgrade the page 1 BIOS image.

See Section 5.6, Updating the BIOS.

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

See Section 2.3.12, Resetting the Netra CP3250 Blade Server.

5.9 Power-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.

5.10 Changing POST Options

These instructions are optional, but you can use them to change the operations that the server performs during POST testing.

1. Initialize the BIOS Setup utility by pressing the F2 key while the system is performing the power-on self-test (POST).

The BIOS Main Menu screen is displayed.

2. From the BIOS Main Menu screen, select the Boot menu.

3. From the Boot Settings screen, select Boot Settings Configuration.

4. On the Boot Settings Configuration screen, you can enable or disable the options shown in TABLE 5-2

TABLE 5-2 POST Options
Option	Description
Quick Boot	This option is disabled by default. If you enable Quick Boot, the BIOS skips certain tests while booting, such as the extensive memory test. This decreases the time it takes for the system to boot.
Quiet Boot	This option is disabled by default.
