Hello, Sergey.
You can't flash plain Option ROM with latest bootutil. Bootutil expects FLB format. You may try to "-saveimage" first to expect. Usually plain Option ROM starts from 0x17a-byte offset (FLB header @ 0xd7). At offset 0xe0-0xe3 you may find ROM length.

Hello!
I have Intel CT Desktop Adapter (vendor ID: 8086, device ID:10d3, chipset 82574L) with 2mbit flash ROM.
So, I've built iPXE image for my NIC without any problem:
> make bin/808610d3.rom
Then made bootable USB with FREEdos & copy bootutil + my image rom on it
The problem occured when I've tried to write my image in NIC's ROM:
> bootutil.exe -nic 1 -restoreimage -file 808610d3.rom
And got the following error:
Invalid image file 808610d3.rom
Please help!
What does it mean? I don't think that image file has invalid format.
May be my NIC has some protection against rewriting?
Thanks in advance
Best regards,
Sergey
