BIOS/EFI Firmware Update Tool
The development kit EFI firmware can be upgraded/reflashed using either of two
methods:
• A standalone SPI programmer
• AMI Firmware Update (AFU) utilities
— afuwin
— afudos
— afulnx
— afuefi
These utilities are free tools available on AMI's web site at
http://www.ami.com/support/product.cfm
Go to the "Product Support" page, select "Aptio" in the AMIBIOS drop down box and
click "Submit".
A Readme file on how to use the tools can be found on the download page.
Note:
The BIOS installed on the development platform is an EFI-based BIOS hence only the
EFI version of the reflash tool can be used to update the BIOS.
