BIOS Update Using Bootable
Software
If a BIOS update becomes available, you can update the BIOS image on the CRB with a utility
from Intel
®
called the Flash Programming Tool (fpt). This utility can be run from the BIOS
UEFI Shell.
Note:
Prior to using the FPT, confirm that the BIOS is configured so it can be updated via this tool.
Ensure that the option EDKII Menu -> Security -> Relax Security Configuration is set
to “Enabled.”
If, however, the system does not have a working BIOS, a hardware method of reprogramming
the Flash memory must be used. Either an in-circuit SPI bus programmer (described in
Appendix B, “BIOS Update Using an SPI Programmer”
) or an external programmer and the
"BIOS1" Flash part removed from the CRB socket must be used. (See
select the desired Flash part to program. Leave JP22 set to connect pins 1-2.)
The following steps describe how to perform a BIOS update using the currently installed BIOS.
See
. Move JP4 to select the desired Flash part to program. Leave JP22 set to connect
pins 1-2.
Download the Flash Programming Tool from the Intel
®
Business Portal..
Unzip the package and copy the files below to the root directory of a USB Flash drive.
Fpt.efi fparts.txt
Add the new BIOS file to the USB Flash drive.
Power off the CRB, then plug in the USB Flash drive.
Power the board on and stop the UEFI boot process in the UEFI Shell.
Enter
map -r
to show the available drives. In most cases, the USB Flash drive will be
fs0
. If
so, enter
fs0:
to change to the USB Flash drive.
Use the following command to update the BIOS:
Fpt.efi -f <BIOSfilename.bin> -bios -p fparts.txt
After programming is complete, power the board
“off”,
remove the USB Flash drive, and
then power the board on to configure and use the new BIOS.
