Itanium-based System Hardware
An system's bootstrap process involves the execution of four software
· option ROM
· Boot Manager
· (see hpux.efi(1M)).
After the processor is reset, firmware initializes and tests processors
and platform. During initialization, the firmware lets a user inter‐
rupt 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 Man‐
ager, 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
The PA-RSIC bootstrap process involves the execution of three software
· (see pdc(1M),
· (see isl(1M), and
· (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 con‐
trol to the loaded kernel image.
