NetBSD/alpha _VER runs on the following DEC Alpha platforms:
DEC 3000/500-family systems
DEC 3000/300-family systems
Digital AlphaStation 200, 250, 255, and 400 systems
Digital AlphaStation 500 and 600 systems
Digital AXPpci systems (including UDB and Multia)
EB64+-family systems (including Digital EB64+ and third-party
AlphaPC 64 systems)
EB164-family systems (including Digital EB164 and third-party
AlphaPC 164 systems)
Digital AlphaServer 8200 and 8400 systems
If your system is not listed here, it is not supported in this release,
but may be supported in more current versions of NetBSD. Check the
alpha port web pages at <http://www.netbsd.org/> for the most recent
information on this, or ask on the alpha mailing list,
<port-alpha@netbsd.org>.
NetBSD/alpha requires the Digital Unix PALcode, which basically means
that you need to have the SRM console installed on your machine. This
console can be distinguished from the ARC console (which is used to
boot Windows NT) by the fact that it has a command line interface,
rather than a menu-driven interface.
A basic system will fit on a 200 MB disk (including swap) without too
much difficulty, but you will probably want at least 500 MB of disk
to have any level of comfort. You will also need at least 32 MB of
RAM, and you will probably want more than that if you're running X.
We support add-in devices on the PCI, ISA, EISA and TurboChannel buses.
Because NetBSD has an extremely machine-independent device driver
system, many device drivers are the same as used in other ports that
use the same bus. For example, the `de' network card driver is shared
by the i386 and Alpha ports. Some drivers on inspection appear as if
they will work on the alpha but have not been tested because that
hardware was not available to NetBSD testers; these are marked as
`UNTESTED' below. If you have one of these devices, and it does work,
please get in touch with <port-alpha-maintainer@netbsd.org> and let
us know that it works. If it doesn't work, do the same thing and we
can probably fix it pretty easily.
Supported devices by bus type are:
PCI Bus
Graphics Adapters
VGA-compatible video (pcivga)
ZLXp-E1 video (DECchip 21030-based video, tga, NOTE: ZLXp-E2
and ZLXp-E3 boards are not supported in NetBSD _VER.))
Network Cards
DECchip 21x40-family 10 and 100 Mbps Ethernet (de)
DEC DEFPA FDDI (fpa)
PCI LANCE Ethernet (le, UNTESTED)
Efficient Networks ENI-155p ATM (en, UNTESTED)
3Com 3c59x and 3c90x (except 3c906) 10 and 100 Mbps Ethernet (ep)
Intel EtherExpress Pro 10/100B PCI Ethernet (fxp, UNTESTED)
SCSI Controllers
Adaptec 294x, 394x, and aic78x0 SCSI (ahc)
BusLogic 9xx SCSI (bha, Works on Alpha PC164)
Qlogic ISP 10x0-family SCSI (isp)
NCR/Symbios 53c8xx-family SCSI (ncr, NCR825 Doesn't always work)
Miscellaneous Devices
Cyclades Cyclom-Y serial boards (cy, UNTESTED)
PCI-PCI bridges (ppb, tested with the DECchip 21050, but should
work with all bridges and system firmware revisions that
comply with the PCI-PCI bridge specification)
ISA Bus
Network Cards
3Com 3c509 Ethernet (ep)
DEC DE200,DE201,DE202 (le)
DEC DE203,DE204,DE205 (lc)
Miscellaneous Devices
PC-style parallel ports (lpt)
NS16450 and NS16550 UARTs (com)
ISA multi-port 16x50 boards (such as ast, boca--only boca has
been tested)
EISA Bus
Network Cards
DEC DEFEA FDDI (fea)
3Com 3c5xx series (ed, UNTESTED)
SCSI Controllers
Adaptec 274x and aic7770 SCSI (ahc, UNTESTED)
BusLogic 7xx SCSI (bha, UNTESTED)
Turbochannel Bus
Graphics Adapters
CFB video (PMAG-BA, cfb)
SFB video (PMAGB-BA, sfb)
(Note that although these boards are supported by NetBSD/alpha,
since there is no keyboard or mouse support available for the
TurboChannel systems, they aren't very useful.)
Network Cards
DEC LANCE Ethernet (PMAD-AA, le, UNTESTED)
DEC DEFTA FDDI (PMAF-F, fta)
Note that PC-style floppy disk drives are not supported in 1.3
(except to boot from), but are supported to some degree in
NetBSD-current.
Note that some devices, especially ISA-based devices, have to have
certain settings set properly for the install and GENERIC kernels to
detect them. (Once installed, you can always rebuild your own kernel
to detect them anywhere you wish, of course.) Here is a list of such
devices and the necessary settings:
Device Name Port IRQ DRQ Misc
------ ---- ---- --- --- ----
Serial ports com0 0x3f8 4 [8250/16450/16550/clones]
com1 0x2f8 3 [8250/16450/16550/clones]
com2 0x3e8 5 [8250/16450/16550/clones]
Parallel ports lpt0 0x378 7 [interrupt-driven or polling]
lpt1 0x278 [polling only]
lpt2 0x3bc [polling only]
AHA-174x SCSI host adapters (in enhanced mode)
ahb0 any any any
AHA-2X4X or AIC-7XXX-based SCSI host adapters
ahc0 any any any
Bus Logic BT445, BT74x, or BT9xx SCSI host adapters
bha0 0x330 any any
bha1 0x334 any any
MFM/ESDI/IDE/RLL hard disk controllers
wdc0 0x1f0 14 [supports two devices]
wdc1 0x170 15 [supports two devices]
ATA disks wd0, wd1, ...
SCSI disks sd0, sd1, ...
SCSI tapes st0, st1, ...
SCSI and ATAPI CD-ROMs cd0, cd1, ...
For each SCSI and IDE controller found, the SCSI or ATA(PI) devices
present on the bus are probed in increasing id order for SCSI and
master/slave order for ATA(PI). So the first SCSI drive found will
be called sd0, the second sd1, and so on ...
3COM 3x59X or 3COM 3x90X PCI Ethernet boards
ep0 any any [you must assign an interrupt in your
PCI BIOS, or let it do so for you]
Intel EtherExpress 100 Fast Ethernet adapters
fxp0 any any [you must assign an interrupt in your
PCI BIOS, or let it do so for you]

le? 0x300 5 memory at D0000-DFFFF
le? 0x200 10 memory at D8000-DFFFF
You should enter the following SRM console command to enable the device:
>>> isacfg -mk -slot ? -dev 0 -handle DE200-LE -irq0 5 -membase0 d0000 -memlen0 10000
-iobase0 300 -etyp 1 -enadev 1

You should enter the following SRM console command to enable the device:
>>> add_de205
