 | | On the PC, the main duties of POST are handled by the BIOS, which may hand some of these duties to other programs designed to initialize very specific peripheral devices, notably for video and SCSI initialization. |
 | | During POST, the BIOS must integrate a plethora of competing, evolving, and even mutually exclusive standards and initiatives for the matrix of hardware and OSes the PC is expected to support. |
 | | The POST section, or POST code, is responsible for the tasks mentioned above, and the environment POST constructs for the OS is known as the runtime code, the runtime BIOS, or the runtime footprint. |
