NetBSD/hppa

Overview

NetBSD is a free, open source Unix-like operating system with support for PA-RISC 1.1 32-bit computers in its NetBSD/hppa port since around 2005, called NetBSD/hp700 until the 7.0 release, as a Tier II port.

The port focuses on 32-bit PA-RISC 1.1 computers and 64-bit PA-RISC 2.0 systems in 32-bit. The current effort is largely based on Michael Shalayeff’s work on the OpenBSD/hppa kernel from 2004 to 2005 and updated OpenBSD code later on.

NetBSD/hppa is the least complete port of the three current open source systems, trailing both Linux and OpenBSD on PA-RISC.

NetBSD describes the following systems as supported (in the 9.2 release, as of 2021), unsure if all are completely supported and tested.

Hardware supported

Processors

32-bit PA-RISC 1.0 PA-7000, PA-7100, PA-7100LC, PA-7200 and PA-7300LC; some systems with 64-bit processors in 32-bit mode: PA-8000, PA-8200, PA-8500, PA-8600 and PA-8700.

Buses and chipsets

Most PCI, GSC and Runway buses and onboard bus controllers are supported.

Networking

On--board Ethernet and Fast-Ethernet network interfaces are supported; the FDDI sliders on the 735/755 are not supported. Expansion cards for the GSC/HSC and PCI bus slots with a supported Ethernet chipset (Intel i82596, DEC 21142/43 Tulip, Intel i8255x, Realtek 8120/8139, NE2000, SiS 900) could work.

Realtek RTL8150L USB-based Ethernet adapters are supported.

Storage

Storage I/O is supported via the NCR 53C700 narrow, NCR 53C710 Fast-Narrow or NCR 53C875 Ultra-Wide SE SCSI controllers. The on-board NCR 53C720 Fast-Wide HVD controllers are not supported.

GSC/HSC and PCI expansion cards with one of the 53C710 or 53C8xx (siop) SCSI chipsets, Adaptec 2940 (ahc) PCI and various Qlogic ISP PCI SCSI adapters should also work, however not necessarily for booting.

Graphics

SGC graphics (framebuffer). At the present there is no working X server.

Human I/O

Human I/O is supported via PS/2 and HIL.

Misc

Several PCI USB adapters from VIA and ALi have been tested and are known to work; they support USB mass-storage and Ethernet devices. The onboard Harmony audio system is supported.
