3NetBSD/alpha _VER runs on the following DEC Alpha platforms:
4
5     DEC 3000/500-family systems 
6     DEC 3000/300-family systems 
7     Digital AlphaStation 200, 250, 255, and 400 systems 
8     Digital AlphaStation 500 and 600 systems 
9     Digital AXPpci systems (including UDB and Multia) 
10     EB64+-family systems (including Digital EB64+ and third-party
11        AlphaPC 64 systems) 
12     EB164-family systems (including Digital EB164 and third-party
13        AlphaPC 164 systems) 
14     Digital AlphaServer 8200 and 8400 systems 
15
16If your system is not listed here, it is not supported in this release,
17but may be supported in more current versions of NetBSD. Check the
18alpha port web pages at <http://www.netbsd.org/> for the most recent
19information on this, or ask on the alpha mailing list,
20<port-alpha@netbsd.org>.
21
22NetBSD/alpha requires the Digital Unix PALcode, which basically means
23that you need to have the SRM console installed on your machine. This
24console can be distinguished from the ARC console (which is used to
25boot Windows NT) by the fact that it has a command line interface,
26rather than a menu-driven interface.
27
28A basic system will fit on a 200 MB disk (including swap) without too
29much difficulty, but you will probably want at least 500 MB of disk
30to have any level of comfort. You will also need at least 32 MB of
31RAM, and you will probably want more than that if you're running X.
32
33We support add-in devices on the PCI, ISA, EISA and TurboChannel buses.
34Because NetBSD has an extremely machine-independent device driver
35system, many device drivers are the same as used in other ports that
36use the same bus. For example, the `de' network card driver is shared
37by the i386 and Alpha ports. Some drivers on inspection appear as if
38they will work on the alpha but have not been tested because that
39hardware was not available to NetBSD testers; these are marked as
40`UNTESTED' below. If you have one of these devices, and it does work,
41please get in touch with <port-alpha-maintainer@netbsd.org> and let
42us know that it works. If it doesn't work, do the same thing and we
43can probably fix it pretty easily.
44

70        PCI-PCI bridges (ppb, tested with the DECchip 21050, but should
71            work with all bridges and system firmware revisions that
72            comply with the PCI-PCI bridge specification) 
73

100    (Note that although these boards are supported by NetBSD/alpha,
101    since there is no keyboard or mouse support available for the
102    TurboChannel systems, they aren't very useful.)
103
104    Network Cards
105        DEC LANCE Ethernet (PMAD-AA, le, UNTESTED)

108Note that PC-style floppy disk drives are not supported in 1.3
109(except to boot from), but are supported to some degree in
110NetBSD-current.
111
112Note that some devices, especially ISA-based devices, have to have
113certain settings set properly for the install and GENERIC kernels to
114detect them. (Once installed, you can always rebuild your own kernel
115to detect them anywhere you wish, of course.) Here is a list of such
116devices and the necessary settings:
117

146        For each SCSI and IDE controller found, the SCSI or ATA(PI) devices
147        present on the bus are probed in increasing id order for SCSI and
148        master/slave order for ATA(PI). So the first SCSI drive found will
149        be called sd0, the second sd1, and so on ...
