Good morning. I have one question: for this method to work I understand I need a Bios "dump".
Are "dump" and "Backup" the same thing?
Do I need a chip programmer to create dumps and/or backups or is there any procedure to execute the dump/backup and upload the patched ones with no additional hardware and no need to open the laptop?

Thank you very much and apologies for the dummy questions, but I couldn't find the answers anywhere.

Thx,
P.
