boot(1M) boot(1M) NAME
boot - bootstrap process DESCRIPTION
Itanium-based System Hardware An system's bootstrap process involves the execution of four software components: o CMOS o option ROM o EFI o Boot Manager o (see hpux.efi(1M)). After the processor is reset, firmware initializes and tests processors and platform. During initialization, the firmware lets a user interrupt and configure CMOS and option ROMs. It then transfers control to EFI, the Extensible Firmware Interface. EFI, in turn, initial- izes EFI boot and runtime services and launches the Boot Manager. The Boot Manager, which allows loading of EFI application or drivers from EFI defined file system, loads and transfers control to the HP-UX-specific bootstrap loader. then loads the HP-UX kernel object file from the HP-UX file system to memory and transfers control to the loaded kernel image. PA-RISC Hardware The PA-RSIC bootstrap process involves the execution of three software components: o (see pdc(1M), o (see isl(1M), and o (see hpux(1M). After the processor is RESET, the (firmware), performs a self-test and initializes the processor. It then loads and transfers control to the operating-system-independent in turn, loads and transfers control to the utility, the HP-UX-specific bootstrap loader. then downloads the HP-UX kernel object file from an HP-UX file system and transfers control to the loaded kernel image.
