NetBSD/Alpha's Status
1996-04-25 08:28:04 +04:00
If you find an inaccuracy in this file, can clarify it in any place,
etc., please send mail to me (cgd@cs.cmu.edu).
1995-04-25 22:59:14 +04:00
Supported hardware:
DEC 3000/[456789]00 (I've only tested it on the 400 and
600, but the rest should "just work) using the following
peripherals:
1996-04-25 08:28:04 +04:00
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)
1995-04-25 22:59:14 +04:00
Things are aren't supported:
No frame buffers of any type.
1996-04-25 08:28:04 +04:00
Other TurboChannel option boards (see the
1995-04-25 22:59:14 +04:00
TODO.users file.)
The ISDN/Audio chip.
DEC 3000/300 family, with same hardware above.
1996-04-25 08:28:04 +04:00
AlphaStation {200,250,255,400} systems using the following
peripherals:
1996-04-25 08:28:04 +04:00
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:
1996-04-25 08:28:04 +04:00
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 600 systems, with the same supported hardware
1996-04-25 08:28:04 +04:00
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.) AlphaStation 500 systems may work, but
have not been tested.
AXPpci systems, with the same supported hardware list as
1996-04-25 08:28:04 +04:00
the AlphaStation {200,250,255,400} systems.
NOTE: As far as I know, testers have not tested current kernels
throughly on DEC 3000/[3-900] systems, or AT ALL AlphaStation 600
systems!
1995-04-25 22:59:14 +04:00
At this time none of the following systems are supported:
1996-04-25 08:28:04 +04:00
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
I was hoping to get a DECpc AXP port working "for free" based on
the PCI work, but the DECpc AXP is a very different (and, in my
opinion, very alien) piece of hardware. If somebody wants to make
NetBSD/Alpha run on the DECpc AXP system, get in touch and I'll do
what I can to help you get started.
1996-04-25 08:28:04 +04:00
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), NetBSD/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:
1995-04-25 22:59:14 +04:00
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.
1996-04-25 08:28:04 +04:00
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.
1995-04-25 22:59:14 +04:00
1996-04-25 08:28:04 +04:00
See your owner's manual for more details on how to set your machine
to use a serial console.
1995-04-25 22:59:14 +04:00
See the file src/sys/arch/alpha/README to find out how to get the
1996-04-25 08:28:04 +04:00
latest sources and binaries.
1995-04-25 22:59:14 +04:00
Please see the file src/sys/arch/alpha/TODO.users for a list of things
that users can do to help NetBSD/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.
