[ATsai15]

hello

I designed a Thunderbolt dock with i210AT LAN. I want to know how to modify the "subsystem vender ID" and "subsystem ID." I tried to run lanconfw64e.exe but cannot save.

Appreciate your help.

Dear Carlos

in section 2.23

---------------------------------------------------------------------------------------------------------------------------------------------

Not all fields in the image are protected. Fields that are normally subject to change by the OEM, such as

the MAC address, PCI subsystem ID fields and LED customizations, can be changed without invalidating

the digital signature.

----------------------------------------------------------------------------------------------------------------------------------------------

I can program the MAC address. But I don't know how to change the PCI subsystem ID field. Do I need pull down the pin12 to unlock the security?

hi

I already knew the answer. Just use lanconf to change the offset 0xC.
