POST routines are part of a computer's pre-boot sequence. If they complete successfully, the bootstrap loader code is invoked to load an operating system . In IBM PC compatible computers, the main duties of POST are handled by the BIOS or UEFI .
The original motivation for EFI came during early development of the first Intel–HP Itanium systems in the mid-1990s. BIOS limitations (such as 16-bit real mode, 1 MB addressable memory space, [7] assembly language programming, and PC AT hardware) had become too restrictive for the larger server platforms Itanium was targeting.

[74] Some CPUs and ...
