OpenBSD/hp300 runs on most of the HP 9000 series 300 and 400 workstations, based
on the Motorola 680x0 processor family.
The OpenBSD/hp300 port has been discontinued after the 5.5 release.
|
History:
OpenBSD follows in the footsteps of 4.4BSD by supporting the hp300; most
types of machine are supported with 68030 or better processors, along with
SCSI and HP-IB storage devices.
OpenBSD/hp300 runs 8k pagesize executables natively (the first operating
system for the hp300 to do so), maintaining the standard binary format
used by all other OpenBSD m68k platforms.
Over time, the 4.4BSD codebase was extended and corrected, and the hp300
port switched to the regular config(8) for kernel configuration.
Shortly after OpenBSD 2.9 was released, support was added for the 425e model,
using a serial console on the first serial port.
Later development featured the replacement of the old hp300-specific SCSI code
base with the generic SCSI subsystem (as of 3.6), dynamic attachment and
detachment of HP-HIL devices, and support for the SGC bus and frame buffers
(as of 3.7), as well as the Apollo Domain keyboard and mouse (as of 3.8).
Current status:
Currently, all the hardware listed in the
supported hardware section below boots
multi-user, and supports enough of the on-board devices to be generally
usable, unless specified otherwise.
A native, unaccelerated X11R6 server is available for all supported frame
buffers except the
sti
frame buffers.

Unsupported machines
- 68010-based: 310
- 68020-based: 318, 319, 320, 330 and 350
(support for all 68020 models has been dropped after OpenBSD 3.9)
- 68030-based: 332
(this model ought to work if a 68882 FPU is installed, but to the
best of our knowledge this has never been tried)
Unsupported devices
- Parallel port.
- 98765 TurboVRX, X-Genesis and Y-Genesis frame buffers.
- ISA slot on the 4xx "t" models.
(There is minimal support for it, but interrupts are not working)
- EISA slots on the 4xx "s" models.
Getting and installing OpenBSD/hp300:
