OpenBSD/hppa

This port is aimed to support the following HP 9000 models: 705, 710, 712, 715, 720, 725, 730, 735, 750, 755, J200, J210, C100, C110 (bold means "known to be working"). Other similiar to those hardware configurations may be supported as far as if they based upon:

• HP PA-RISC 70000, 7100, 7150, 7100LC, 7200 processors (7250 and 7300LC may work too);
• Viper (others ?) memory controller;
• LASI, ASP, WAX bus/IO controller;
• and EISA bus controller;
• NCR53C700, NCR53C710, NCR53C720 SCSI I/O Processor;
• Venom, CRX-8, CRX-24, HCRX-8, HCRX-24 video controllers;
• HIL or PS/2 keyboard and mouse;
• EISA devices will work, but they won't be usefull for booting, but some of those manufactured by HP for 700/800 systems.

• pa8k-based systems (in 32-bit mode);
• HP 9000 834, 835, 836, 844, 845, 846;
• HP 9000 E23, E35, E45, E55;
• HP 3000 908, 918, 928, 938;
• Hitachi VQ200, VQ210, and some other non-HP workstations;
• Precision Book from RDI Computer Corporation (well, unlikely)
• HP VME and VXI single board systems (requires VME at least)

Status:

History:

• STI (*CRX-*) graphics boards
• LASI, ASP, WAX and EISA bus adapters
• com, lpt, fdc drivers (no fd yet ;)
• PDC driver
• kernel bootstrap working
• network boot working through the LIF image
• cross-tools compiling/working

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=hp700 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/DISKLESS/bsd.
Kernel cross-build process is similiar to the one for boot, consult config(8) and options(8) for kernel build options and configuration.

1. Server setup


• rbootd must be setup and started
  
  • /etc/rbootd.conf contains a single line per machine you ented to boot from the server. Each line contains the ethernet address of the client hppa machine, and the filename to be loaded from the tftp server. For example:

    	8:0:9:70:c4:11    boot.lif    # 9000/720
    	8:0:9:19:fb:a0    boot.lif    # 9000/725
    	

• For further reading on server setup for network booting in general, see also: diskless(8).
2. Client Network Boot


• BOOT_ADMIN
  In order to get to the BOOT_ADMIN prompt, you must hit \ as the machine is coming up. Once it probes bootable devices, type 'a' for the 'BOOT_ADMIN' prompt.
• network boot command
  Once at the 'BOOT_ADMIN' prompt, type:

  	BOOT_ADMIN> boot lan isl
  

  ... and you are on your way to booting boot.lif!
