Using Dell Update Packages 27
You can enable two types of updates in the UEFI environment:
Update of platform firmware for supported devices
—the only available
updates are for the USC, drivers, and diagnostics.
Use the USC Platform
Update wizard to display a list of available updates for your system.
After you select the updates you want to apply, the USC downloads and
applies the updates.
You can download updates:
from the Dell FTP server
from a locally configured FTP server. You must have access to
ftp.dell.com
to download the updates that are hosted by the local
FTP server.
by using a proxy server to access an FTP server
from a USB device.
NOTE: See the Unified Server Configurator User’s Guide available on the Dell
Support website at support.dell.com for more information on USC.
Run the Platform Update wizard to ensure that you have the most current
drivers before installing the operating system. You can also use the
Platform Update wizard to update the diagnostics utility.
Update of applications stored on the
flash storage space
—Applications
such as UEFI and Diagnostics are updated in the UEFI environment.
You can update any component, for example BIOS, in both the UEFI and
customer operating system environment. After it is updated successfully in
the customer operating system environment using DUPs, you can enter the
UEFI environment and rollback the component to the version that was
previously installed before the update occurred.
Platform firmware rollback to the previous version is supported in the
UEFI environment. If your operating system has a non–functioning
application because of a BIOS or firmware flash, reboot to the
UEFI environment and roll back to the previous version.
To support the rollback feature in the UEFI environment, a firmware image
repository for all devices that can be updated in the UEFI environment is
placed on the flash storage space. If you decide to update any device in the
UEFI environment, the update package of the corresponding device is
downloaded from the source location specified by you. Versions from the life
cycle log (LCL) are compared to the online catalog from the Dell FTP site.
The LCL has records of firmware versions for devices that are updatable in
