Generally, a hypervisor implies a VM which multiplexes the hardware and allows multiple OSes to run at once, which is more than any BIOS has ever done. Also, a hypervisor generally doesn't provide any hardware abstraction, to be compatible with existing OSes which expect to be alone on the hardware.
