OpenBSD/MACHINE OSREV runs on the following classes of machines:
- sun4 -- 4/100, 4/200, and 4/300. (note that support
for the 4/400 processor is incomplete)
- sun4c -- SS1, SS1+, SS2, IPC, ELC, IPX, and SLC
- sun4m -- Sun Sparc Classic, LX, 4, 5, 10, 20, and 600MP
- Tadpole SPARCbook 3GS, 3GX and 3XP
- Force CPU5V
- as well as faithful clones of the above Sun systems, such as:
+ Aries Research Inc, Parrot II
+ Axil 243, 245, 320 (and possibly other models)
+ Opus 5000, 5250
+ TWS,SuperCOMPstation-20S
+ Tatung micro COMPstation 5, COMPstation LX
+ RDI BrideLite and PowerLite
+ DTKstation/Classic+
+ Transtec SS5/170
For sun4m machines, the following Mbus CPU modules are supported:
- SM30, SM40, SM41, SM50, SM51, SM51-2, SM61, SM61-2, SM71,
SM81, SM81-2
- SM100
- Ross RT620/RT625 at 90, 125, 150 or 166 MHz
OpenBSD/MACHINE OSREV does NOT run on these machines (yet):
- Sun 4/400
Lacking support for the I/O cache, and related
ethernet problems.
- sun4d -- SPARCcenter 2000, SPARCserver 1000
XDBus and multiprocessor support issues.
- sun4u (Ultrasparcs)
These machines are supported by the OpenBSD/sparc64 port.
- clones that are significantly different from the Sun systems
(e.g. K-Bus based Solbourne)
The minimal configuration requires 4M of RAM and ~60M of disk space.
To install the entire system requires much more disk space, and to run
X or compile the system, more RAM is recommended. (OpenBSD with 4M of
RAM feels like Solaris with 4M of RAM.) Note that until you have
around 16M of RAM, getting more RAM is more important than getting a
faster CPU.) Installation from "ramdisk" kernels requires 8M of RAM.
Supported devices {:-include-:}:
sun4c and sun4m SBus video:
cgsix (GX, GX+, TGX, TGX+), cgthree, and bwtwo frame buffers
sun4m on-board machine specific video:
TCX, cgfourteen (aka SX), p9100 (Tadpole 3GS, 3GX)
sun4 video (not thoroughly tested...):
P4 -- on-board bwtwo, cgfour, cgsix, cgeight
VME -- cgtwo, cgthree, cgsix
serial ports:
ttya and ttyb (can be used as console if needed),
ttyc and ttyd (Sun 4/300 only)
SBus magma serial port cards, including:
4Sp, 8Sp, 12Sp, 16Sp, LC2+1Sp, 2+1Sp,
4+1Sp, and 8+2Sp.
SBus Serial Parallel Interface (SUNW,spif)
ethernet:
on-board AMD Lance ethernet ("le0"),
SBus AMD Lance ethernet cards,
on-board Intel 82586 ethernet (ie0 on 4/100's and 4/200's),
VME Intel 82586 ethernet cards
SBus SunSwift and Quad FastEthernet cards (hme, qfe)
SBus FastEthernet cards (qec+be)
SBus QuadEthernet cards (qec+qe)
SCSI:
on-board "esp" SCSI controller (sun4c's, and the 4/300),
SBus "esp" SCSI controller (including 3rd party compatibles),
Sun "SUN-3"/"si" VME SCSI controller (polled mode only, slow),
Sun "SCSI Weird"/"sw" on-board controller (4/110 only, polled)
VME disks:
Xylogics 7053 VME/SMD disk controller ("xd"),
Xylogics 450/451 VME disk controller ("xy")
[note: VME/IPI disks are not supported]
Audio:
sun4c/Classic AMD audio.
sun4m (ss4/ss5) CS4231 audio.
Miscellaneous devices:
Sun floppy disk drive on sun4c machines.
Sun keyboard and mouse.
Sun SBus Expansion Subsystem (SUNW,xbox)
Tadpole microcontroller (tctrl)
Force FGA5000 SBus/VME bridge
Force system configuration registers
Force flash memory
Hardware the we do NOT currently support, but get many questions about:
Multiprocessor machines (Will not boot correctly on multiple CPU sun4m)
Audio driver for some sun4m machines (LX,ZX,ss10,ss20)
Floppy driver for sun4m (can boot/install from ramdisk floppies though)
Interrupt driven SCSI driver for Sun 4/100's and 4/200's
VME mti 16-port serial card
VME alm2 16-port serial card
VME mcp 4-port serial card
VME IPI controller
VME cgfive framebuffer
VME cgnine framebuffer
VME GP/GP2 Graphics Processor
SBus cgeight framebuffers
SBus GS framebuffer (aka cgtwelve)
SBus GT framebuffer ("Graphics Tower")
SBus ZX framebuffer (aka Leo)
Tadpole onboard PCMCIA and modem
The supplied GENERIC kernel is the best attempt at a configuration that
works on the widest range of machinery (sun4, sun4c, and sun4m).
If you have problems with the OpenBSD OSREV kernel in this distribution,
please visit the OpenBSD web page (http://www.openbsd.org) and the mailing
lists to review the current status and check for updates and distribution
errata.
If you have Sparc hardware you can donate or make available at nominal
cost, please mention this on the lists, many things aren't being tested
or developed simply because developers usually have only a Sparcstation
at hand, not an array of systems. Donation or mid/long term loan of
UltraSparc (sun4u) or HyperSparc (sun4m) systems would help ensure the
long-term viability of OpenBSD on Sparc based systems.
Your support in terms of documenting previously unknown problems with
OpenBSD/MACHINE, helping debug known problems, implementing missing pieces,
and testing OpenBSD on various architectures is actively encouraged.
The OpenBSD mailing lists, web-pages and sendbug utility are your best
tools for helping make OpenBSD/MACHINE a better release.
