It's similar to HP9000 systems, see

- POST
- EFI (boot menu)
- EFI boot loader from disk
- load kernel
- load OS

Hope this helps!

Re: integrity boot process?

Hi,

Adding to torsten, after POST, PAL/SAL (processor abstraction layer and system abstraction layer) that provides initial hardware tests. BCH replaced by EFI boot manager in integrity and hpux.efi loads the kernel. After init spawns processes, the booting procedure is consistent on fusion releases 11.23 (updated) and 11.31.

Re: integrity boot process?


Hi
Please find some detained info IPF system boot.This shows How it differs from hp 9000 PDC/BCH

The IPF bootstrap process involves the execution of the following software components in that order:

â ¢ CMOS
â ¢ option ROM
â ¢ EFI
â ¢ EFI Boot Manager (EFI main menu)
â ¢ HP-UX Bootloader (hpux.efi)

After the processor is reset, firmware initializes and tests processors and platform. 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 allowsloading of EFI application or drivers from EFI defined file system, loads and transfers control to hpux.efi, the HP-UX-specific bootstrap loader. hpux.efi then loads the HP-UX kernel
object file from the HP-UX file system to memory and transfers control to the loaded kernelimage.
