OpenBSD/hp300


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 will be 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.

Recent development features 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.


Supported hardware:

(*) SCSI-2 devices are known to work, but may require changing a jumper to restrict them to SCSI-1 behaviour. Refer to your hardware documentation for details.
