[김유석]

Dear Sir.

Currently,

I was successed the read a serial number, and product name useded the 
DMI, in kernel space and user space.

- kernel space.

use the "dmi_get_system_info()"

- user space

use the "dmidecode"

- coreboot space

I don't know any soultion.

READ is OK.

But, i want to write or chage the serial number.
But, i can't found the any solution.

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.
