$OpenBSD: STATUS,v 1.5 1996/10/30 22:37:54 niklas Exp $
$NetBSD: STATUS,v 1.5 1996/09/06 04:01:37 cgd Exp $
OpenBSD/Alpha's Status
If you find an inaccuracy in this file, can clarify it in any place,
etc., please send mail to me (niklas@appli.se).
Supported hardware:
DEC 3000/[456789]00 (I've not tested them, but they should
"just work") using the following peripherals:
Supported hardware:
Built-in serial ports
Built-in LANCE ethernet.
Built-in SCSI chips (53c[f]94), though both
may not work at the same time.
Things that may work but haven't been tested:
TurboChannel option slot LANCE (PMAD-A)
Things are aren't supported:
No frame buffers of any type.
Other TurboChannel option boards (see the
TODO.users file.)
The ISDN/Audio chip.
DEC 3000/300 family, with same hardware above.
AlphaStation {200,250,255,400} systems using the following
peripherals:
Supported hardware:
NCR 53c810 SCSI (built-in or PCI board).
Built-in ns16550 serial ports.
DC21040-based ethernet (built-in or PCI board).
DC21140-based PCI ethernet boards.
DC21050-based PCI-PCI bridges (though other
types of PCI-PCI bridges should work).
PCI VGA video boards.
DEC ZLXp-E1 (DC21030-based, "TGA") video boards.
Keyboard.
PS/2-style mice.
Things that may work but haven't been tested:
Built-in parallel ports.
ISA ns16x50-family serial port boards.
ISA ns16x50 multi-port serial boards.
Other NCR 53c8xx SCSI boards.
Things that ARE NOT supported at this time:
ISA VGA boards.
Sound hardware (including Windows Sound System
built-in on some machines).
DEC ZLXp-E2 and ZLXp-E3 PCI video boards.
Other PCI boards.
AlphaStation 500 and 600 systems, with the same supported
hardware list as the AlphaStation {200,250,255,400} systems.
(NOTE THAT THAT MEANS THE AlphaStation 600's BUILT-IN SCSI
CONTROLLERS DO NOT WORK. You'll need to get a 53c810 board,
or run diskless.)
AXPpci systems (including Multia), with the same supported
hardware list as the AlphaStation {200,250,255,400} systems.
At this time none of the following systems are supported:
DECpc AXP 150 systems (EISA-bus PC-like systems)
Alpha "server" systems (other than perhaps the
AlphaServer 400, which might be an AlphaStation 400
in disguise).
Multiprocessor Alpha systems
Console frame buffers & keyboard are supported only with the frame
buffers and keyboards mentioned as supported above. On other systems
(including all TurboChannel-based machines), OpenBSD/Alpha _must_ be used
with a serial console. To configure various Alpha systems to use a serial
console, do the following depending on the model:
DEC 3000/[4-9]00's:
Flip the appropriate switch on the back of the machine.
DEC 3000/300 family machines:
Boot the machine with the keyboard/mouse connector
unplugged.
DECpc AXPs, AlphaStations, and AXPpci systems:
Get to the console prompt. Set the variable
"console" to be "serial", and "init" or power cycle
the system.
See your owner's manual for more details on how to set your machine
to use a serial console.
See the file src/sys/arch/alpha/README to find out how to get the
latest sources and binaries.
Please see the file src/sys/arch/alpha/TODO.users for a list of things
that users can do to help OpenBSD/Alpha improve. If you're interested
in doing any of them, or porting to new hardware, get in touch and
I'll do what I can to help.
