I lost sku number of my M700 tiny. I need help.

I have a M700 tiny.
I found a way to mod cpu micro code on a site in china.
I lost the sysem information after trying bios mod without fully understanding it.
I should have edited and executed AUTOEXE.bat(attached), but i didn't modify,
so I lost my own system informatio.


The lost information are
  - serial no.
  - machine type and model id
  - system brand id
  - bios(system) sku id
  - preinstalled OS license code (I think it is motherboard id)
  - OA3 License Key ID

I found S/N and Machine Type and Model ID at Chassis.
And  I guess System brand ID is "ThinkCentre M700 Tiny"

I Can't find sku number. How can i found it?
Can I recover license key ID?
