1. go into the bios (hold down F5 during boot)
2. go here and look up your processor Intel:
ARK | Your source for information on Intel products
I don't have a link handy for AMD.

unfortunately i am not working on a Intel processor but on a DSP. All i have is this log which i captured during the booting.

This does not mention L2, but with the CPU name, you can contact the manufacturer for details.

Edit: Did it for you, here you go:
