I try to find the some API in kernel source tree. for example) grep
"dmi_set" * -Rn
But can't found the API.
*Question.*
How to write or change the serial number using DMI? in kernel or in
userspace or in coreboot?
Thank you.
I am not entirely sure what you want - but if you use menuconfig the
regular option to set a serial number is:
MAINBOARD_SERIAL_NUMBER under "System Tables"
You have to have "Generate SMBIOS Tables" enabled as well.
AFAIK it is not currently possible to dynamically update it.
