Nobody has ever accessed a bios by pressing f2 on booting up any computer ever manufactured. What they did access and do access is the CMOS. Completely different thing, and anyone who has spent a considerable number of years using versions of DOS separate from windows and screen readers with speech synthesizers can prove that. Bios writes have to do with screen output and differ from faster screen writes. The difference with the older screen readers is that those were able to handle bios writes fine but the faster screen writes either couldn't be handled or could be handled with difficulty. Every agt game ever made had a run program with it and when you played the game with something like run tark /bios then the screen reader could speak. Also int10 writing in assembly language is bios screen writing. The Cmos is a memory chip that holds a computer's time and date and information about hard drive and other peripherals.
