4NetBSD/alpha _VER runs on the following DEC Alpha platforms:
5
6     DEC 3000/500-family systems 
7     DEC 3000/300-family systems 
8     Digital AlphaStation 200, 250, 255, and 400 systems 
9     Digital AlphaStation 500 and 600 systems 
10     Digital AXPpci systems (including UDB and Multia) 
11     EB64+-family systems (including Digital EB64+ and third-party
12        AlphaPC 64 systems) 
13     EB164-family systems (including Digital EB164 and third-party
14        AlphaPC 164 systems) 
15     Digital AlphaServer 8200 and 8400 systems 
16
17If your system is not listed here, it is not supported in this release,
18but may be supported in more current versions of NetBSD. Check the
19alpha port web pages at <http://www.netbsd.org/> for the most recent
20information on this, or ask on the alpha mailing list,
21<port-alpha@netbsd.org>.
22
23NetBSD/alpha requires the Digital Unix PALcode, which basically means
24that you need to have the SRM console installed on your machine. This
25console can be distinguished from the ARC console (which is used to
26boot Windows NT) by the fact that it has a command line interface,
27rather than a menu-driven interface.
28
29A basic system will fit on a 200 MB disk (including swap) without too
30much difficulty, but you will probably want at least 500 MB of disk
31to have any level of comfort. You will also need at least 32 MB of
32RAM, and you will probably want more than that if you're running X.
33
34We support add-in devices on the PCI, ISA, EISA and TurboChannel buses.
35Because NetBSD has an extremely machine-independent device driver
36system, many device drivers are the same as used in other ports that
37use the same bus. For example, the `de' network card driver is shared
38by the i386 and Alpha ports. Some drivers on inspection appear as if
39they will work on the alpha but have not been tested because that
40hardware was not available to NetBSD testers; these are marked as
41`UNTESTED' below. If you have one of these devices, and it does work,
42please get in touch with <port-alpha-maintainer@netbsd.org> and let
43us know that it works. If it doesn't work, do the same thing and we
44can probably fix it pretty easily.
45

87

103    (Note that although these boards are supported by NetBSD/alpha,
104    since there is no keyboard or mouse support available for the
105    TurboChannel systems, they aren't very useful.)
106
107    Network Cards

111Note that PC-style floppy disk drives are not supported in 1.3
112(except to boot from), but are supported to some degree in
113NetBSD-current.
114
115Note that some devices, especially ISA-based devices, have to have
116certain settings set properly for the install and GENERIC kernels to
117detect them. (Once installed, you can always rebuild your own kernel
118to detect them anywhere you wish, of course.) Here is a list of such
119devices and the necessary settings:
120

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