Using the Boot Selection Menu program
The Boot Selection Menu program is a built-in, menu-driven configuration utility program that you can use to
temporarily redefine the first startup device without changing settings in the Setup utility.
To use the Boot Selection Menu program, complete the following steps:
Step 1.
Connect a keyboard, monitor, and mouse to the console breakout cable, and connect the console
breakout cable to the compute node.
Step 2.
Turn on the compute node (see "Turning on the compute node" on page 15).
Step 3.
Press F12 (Select Boot Device). If a bootable USB mass storage device is installed, a submenu
item (USB Key/Disk) is displayed.
Step 4.
Use the Up Arrow and Down Arrow keys to select an item from the Boot Selection Menu and
press Enter.
The next time the compute node starts, it returns to the startup sequence that is set in the Setup utility.
Updating the Universally Unique Identifier and DMI/SMBIOS data
After the system board is replaced, you must update the Universally Unique Identifier (UUID) and
DMI/SMBIOS data in the integrated management module II (IMM2) on the new system board.
You can use the Advanced Settings Utility (ASU) and any of the following access methods:
• Locally (in-band)
– Through the Keyboard Controller Style (KCS) interface
– Through the LAN over USB interface
• Remotely over a LAN
You can use the ASU under any supported operating system, or you can use the Bootable Media Creator or
a Windows- or Linux-based toolkit to create bootable media that contains the ASU. For information about the
ASU and instructions for downloading and unpacking the ASU code, see https://support.lenovo.com/us/en/
documents/LNVO-ASU and the Advanced Settings Utility User's Guide.
The following sections provide instructions for updating the UUID and DMI/SMBIOS data, using the different
methods for accessing the IMM2. The following conventions apply to the command syntax:
• Variables are shown in italics.
• Optional parameters are enclosed in brackets ([ ]). Do not type the brackets in the commands. If you
omit an optional parameter, the default is used.
• Although the command syntax is shown in mixed case, the commands are not case sensitive.
Locally: Keyboard Controller Style (KCS)
This access method uses the IPMI/KCS interface. The IPMI driver must be installed; with some operating
systems, the IPMI driver is installed by default. The ASU provides the corresponding mapping layer.
To update the UUID, in the ASU command-line interface, enter the following command:
asu set SYSTEM_PROD_DATA.SysInfoUUID uuid –kcs
where uuid is the user-assigned hexadecimal value, up to 16 bytes, that identifies the compute node.
The --kcs parameter indicates that a kcs channel is used to communicate with the IMM.
To update the DMI/SMBIOS data, complete the following steps:
Step 1.
In the ASU command-line interface, enter the following command:
asu set SYSTEM_PROD_DATA.SysInfoProdName xxxxyyy –kcs
where:
