Initially, the BIOS was needed to service disk drives, a monitor, and a computer. Today it performs much more tasks, including finding the right partition and sector on the drive, setting up the system bootloader. In modern laptop models, manufacturers are increasingly using the new EFI interface instead of the BIOS. His scheme has great potential. For example, routines are now embedded between the operating system and the drive.
