NAME
boot - bootstrap process
DESCRIPTION
Itanium-based Hardware
A Itanium®-based system's bootstrap process involves the execution of four software components:
• CMOS
• option ROM
• EFI
• Boot Manager
•
(see hpux.efi(1M))
hpux.efi
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, initializes 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
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-RISC server and workstation bootstrap process involves the execution of three software com-
ponents:
