The PlayStation 2 BIOS (Basic Input/Output System) is proprietary software owned by Sony Interactive Entertainment.

In most countries (including the US under the DMCA), you are legally allowed to make a backup copy of software you physically own. This includes the BIOS of a console.

Illegal: You do not own a PS2. You download a BIOS file from MediaFire, Mega, or a ROM site.
