What do you mean ? Do you need my bios file backup?

If is possible I need the ability to enable and disable onboard ram by BIOS

Attached is the backup of my bios

Thanks

I am a technician but I have never made bios changes, I have always modified the motherboard electronically.
This time I can't do it and I have to do by bios (because I need some times to turn ON onboard RAM and sometimes turn it OFF) but I don't know how to do it. I don't have any others tool.
If you can explain it to me with more detail it would be a great pleasure to me.
Thank you
