NetBSD/pmax notes on System Models

Contents

These are the systems that NetBSD/pmax supports:

Work is currently under way for the following system:

NetBSD/pmax currently does not support the following systems:

A DECstation is a workstation that has some form of graphics display, keyboard and mouse. A DECsystem is a server that uses a serial console. Many models can be used in either form, usually by adding or removing the graphics card or video memory.

DECstation family has various TURBOchannel option cards which also work with TURBOchannel based Alpha AXP family. NetBSD/pmax currently supports some of option cards.

Here is a list of Board, System Type, Code and Model Names and list of known PROM revisions with their netboot status.

The 1 MB Prestoserve NVRAM card is also standard with the DECsystem 5900 and 5900-260.

DECsystem 5500

The DECsystem 5500 is shipped in a BA430 enclosure, which provides a 12-slot backplane and room for four mass storage devices. The base system contains the following:
  • A KN220-AA module set. This consists of a KN220 I/O module in slot 1 and a KN220 CPU module in slot 2.
    The CPU module contains:
    • 30 MHz R3000 CPU with R3010 FPU.
    • 512 kBytes of Prestoserve battery backed RAM.
    The I/O module contains:
    • Q22-bus interface
    • SGEC Second Generation Ethernet Controller
    • DSSI Digital Storage System Interconnect port
    • SII-based SCSI port.
  • From 1 to 4 MS220-AA 32MB memory modules, installed in slots 3 through 7.
    64MB memory modules are also available (part number?).

DECsystem 5400

The DECsystem 5400 is based on the 3500-series MAYFAIR VAXes. The 3500-series VAXes are supported by NetBSD/vax and that port may be able to be leveredged for a DECsystem 5400 port.

DECsystem 5810, 5820, 5830 and 5840

The DECsystem 5800-series is based on the VAX 6000 model 300. The VAX 6000 model 300 is supported by NetBSD/vax and that port may be able to be leveredged for a DECsystem 5800 port.

  • DEFTA PMAF-F PDQ Fibre Optic FDDI interface There are variations of SAS or DAS.

Unsupported Option Cards

The wide variety of TURBOchannel option cards was manufactured for DECstation 5000 as well as DEC3000. The following are not supported by NetBSD/pmax in this moment.
  • PMAGB-J 8bpp/24bpp direct color non-accelerated (TX)
    1280x1024 @ 72 Hz
  • DEFZA PMAF-A/PMAF-C FDDIcontroller 700 interface
    Older FDDI interface card prior to DEFTA. There are variations of connectors; DAS, SAS, Copper ThinWire and Shielded Twisted Pair (STP). This may just be a case of testing the card. If it doesn't work, support should not be too hard to add.
  • AV01B-AA DECaudio card and distribution box (LoFI)
  • PMAGD-AA/PMAGD-BA 8bpp or 24bpp accelerated framebuffer (HX+)
    TURBOchannel brothers of PCI TGA. Screen resolution is selectable by a rotary switch.
  • PMTNV-A Prestoserve NVRAM
