This port is aimed to support the following HP 9000 models: 705, 710, 712, 715, 720, 725, 730, 735, 750, 755, J200, J210, J210XC, C100, C110, B132L, B160L, B180L, C132L, C160L, C180L (bold means "known to be working"). Other similiar to those hardware configurations may be supported as long as if they based on: Systems which may work (eventually):
Hardware is needed for this project, see "Wanted List". (contact mickey).


Have system autoconfig using bootable images, heading for single-user.


This project was started in one of those days when the only open source operating systems for HP PA-RISC computers were Lites and MkLinux. These two sources were a major supply of information and code for initial development of the OpenBSD/hppa port. The HPBSD is encumbered by HP proprietary code and USL licensing and is not publicly available. One of the major direct benefits from previous porting efforts (besides the code, of course ;) is support for HP PA-RISC in GCC and binutils, which allowed quick build of cross-tools environment for development.

Later on HP decided to sponsor a Linux port to PA-RISC machines which actually resulted in some proprietory documentaion release, even they target different class of 9000 machines.

So far here is a history of OpenBSD/hppa port (it has no dates, but use cvs to see what happened when):


(most of which was released by HP for the Linux/parisc project):
    1. PA7100LC CPU ERS
    2. PA7300LC CPU ERS
  2. Processor Dependent Code/I/O Dependent Code Interface
    (selected chapters from "PA-RISC I/O Architecture Specification")
    1. PDC 1.1
    2. IODC 1.1
    3. Version and Identification Number Allocation
    4. Memory Data Formats 2.0
    5. PDC Procedures 2.0
    6. PDC Entry Points 2.0
    7. OS Interface 2.0
  3. Bus controllers/bridges/adaptors
    1. LASI Core Bus Adapter (including lan, scsi, serial, lpt controllers)
    2. Dino PCI bridge, and Errata
    3. Elroy ERS (Edited for Open Source)
    4. Astro Overview, Error handling,R2I Operations, Registers Map, Runway Interface, System Mamory Map
  4. Stinger graphics
  5. NCR 53C700/710/720 SCSI I/O Processors (the doc is actually for 770, which is claimed as compatible)
  6. Intel i82596DX/SX and i82596CA Ethernet Controllers

Build cross-tools:

cd /usr/src
sudo make TARGET=hppa cross-tools

cross-tools build process may fail in the libc stage, consider that's all right, since libc support is not finished yet.

Build boot.lif file using cross-tools:

cd /sys/arch/hppa/stand
make obj
set cross=(/usr/cross/hppa/usr/bin)
make MACHINE=hppa MACHINE_ARCH=hppa \
	"AS=$cross/as" "CC=$cross/cc" \
	"CPP=$cross/cpp" "LD=$cross/ld" \
	"AR=$cross/ar" "STRIP=$cross/strip" \
	"LORDER=$cross/lorder" "NM=$cross/nm" \
	"RANLIB=$cross/ranlib" "SIZE=$cross/size"

One will have a boot.lif file to boot then in the obj-directory. That image may include diskless kernel image if one was available in the sys/arch/hppa/compile/SHEPHERD_PIE/bsd.
Kernel cross-build process is similiar to the one for boot, consult config(8) and options(8) for kernel build options and configuration.

In order to use the boot.lif files you must prepare your server and instruct your machine to boot off the network:
  1. Server setup

  2. Client Network Boot
