Chapter 2 Installing the Server
Configuring BIOS Settings and Updating BIOS Firmware
Updating the BIOS Firmware From A Linux Operating System
Use the following procedure to update the BIOS firmware from a running host OS.
Note The required version of the iFlash32 utility that is used in this procedure is iFlash32 Version 1.1, Build 3
or later. This utility is included in the BIOS firmware update package. See
Determining the iFlash32
Utility Version and Build, page 2-18.
Step 1 Boot the server using a hard drive that has the Linux host OS installed.
Step 2 Download the BIOS update package for Linux and the C200 server from Cisco.com and extract it to a
temporary folder on the server’s host OS.
To find the downloads for your server, see the following URL, then click Unified Computing, log in,
and then click Cisco UCS C-Series Rack-Mount Servers.

Note Alternatively, if you do not have a browser installed on the server, you can download the package to a
separate computer and then transfer the files by using a USB thumb drive. If you use this method, copy
the contents of the extracted
Linux folder to the root directory of the USB thumb drive, then insert the
thumb drive into a USB port on the C200 server.
Step 3 Change directory to the folder that contains the BIOS update package.
• If you extracted to a location on the host OS, change directory to that folder, then continue with
Step 4.
• If you are transferring the files with a USB thumb drive, perform the following steps:
a. At a Linux prompt, enter the following command to verify that the USB thumb drive is detected:
fdisk -l
If the thumb drive is detected, it appears as /dev/sdb1 in the list of detected SCSI devices.
b. Mount the USB thumb drive as a directory in the Linux file system:
mount /dev/sdb1 /mnt/usb
c. Change directory to the folder on the USB thumb drive that contains the BIOS update package.
For example:
cd /mnt/usb/c250
Step 4 Run the iFlash32 utility to update the system BIOS in non-interactive mode by entering the following
command and options:
iflash32 - ./iflash32 -u -ni [BIOS file name].cap
See the “iFlash32 Utility Command Options” section on page 2-18 for information about the available
options.
Step 5 Reboot the server to complete the update.
