For more than 20 years, the PC has relied on the BIOS (Basic Input/Output System), a small set of fixed software routines normally built into a chip on the motherboard. This hangover from a distant past is causing more and more problems, said Mark Doran, Intel's principal engineer behind the Extensible Firmware Interface (EFI) that aims to humanely kill the antique technology.
"When I started, I got senior managers together from across Intel and asked them what would happen if we had a blank sheet of paper to replace the BIOS," Doran said. "It turned into a three-day bitch session." He said that the original designers of the IBM PC BIOS had no idea that it would survive this long. "They thought that 250,000 machines would see it through to the end of its life," he said.
