??? Where did I claim that? Current BIOSes do, however, check RAM, existence of peripherals, keyboard, etc. Modern OSes also do all that. I'm not advocating all removal of the BIOS--it is needed. I just think that the BIOS is doing things it no longer needs to do.
Also BIOS(some) have a a remedial anti-virus/anti-flash built in... for security... i have successfully modded a few bios and know a thing or 2 about them.
