How do I set the Main setup option Word 0x30 FSD to 1000Mb full duplex.  My BIOS doesn't support this directly.  Is it possible with bootutil?

 

Thank you.

Hello, @ajb 

You can use the Bootutil to dump the NVM image, perform the modifications and then upload the image, but you would need to re-calculated the total checksum, and update the checksum value in word 0x3F by yourself.

Other option you can try is using the ethtool to alter the eeprom contents similar to how they make an MAC address change here: https://blog.kanbach.org/post/how-to-permanently-change-a-mac-address-using-ethtool/
