.\" $NetBSD: hardware,v 1.9 2000/03/21 10:50:03 soda Exp $ .Pp NetBSD/alpha \*V runs on most of the .Tn DEC Alpha PCI platforms, on all of the TURBOChannel models, on the high end 8200 and 8400 systems, and on the 4100 series. .Pp The SRM console is required. 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. The SRM prompt is ``\*>\*>\*>''. .Pp Some platforms have both the SRM console and the ARC console, and can switch between them, and other platforms have only one type of console loaded at any one time. If your system comes up with the ARC firmware, it may be possible to switch it to SRM with a menu or to download SRM from .Lk ftp://gatekeeper.dec.com/pub/Digital/Alpha/firmware/index.html . You may want to buy a firmware update CD from Compaq Computer Corporation. .Pp More information on supported platforms and devices can be found on the alpha port web pages at .Lk http://www.netbsd.org/ "" . .Pp 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. .Pp Although it is actually possible to boot and install NetBSD/alpha in only 16 MB of RAM, you will want to have at least 32 MB. . . 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 .Em untested below. If you have one of these devices, and it does work, please get in touch with .Mt 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. .Pp Supported devices by bus type are: .Bl -bullet -compact .It PCI Bus .Bl -bullet -compact .It Graphics Adapters .Bl -hyphen -compact .It VGA-compatible video (pcivga) .It ZLXp-E1 DECchip 21030-based video, .Em tga .(Note ZLXp-E2 and ZLXp-E3 boards are not supported in .Nx \*V . .Note) .El .It Network Cards .Bl -hyphen -compact .It DECchip 21x40-family 10 and 100 Mbps Ethernet (de) .It DEC DEFPA FDDI (fpa) .It PCI LANCE Ethernet (le, UNTESTED) .It Efficient Networks ENI-155p ATM (en, UNTESTED) .It 3Com 3c59x and 3c90x (except 3c906) 10 and 100 Mbps Ethernet (ep) .It Intel EtherExpress Pro 10/100B PCI Ethernet (fxp, UNTESTED) .El .It SCSI Controllers .Bl -hyphen -compact .It Adaptec 291x, 2920, 2930C, 294x, 295x, 39xx, 19160, 29160 and AIC-78xx SCSI (ahc) .It BusLogic 9xx SCSI (bha, Works on Alpha PC164) .It Qlogic ISP 10x0-family SCSI (isp) .It NCR/Symbios 53c8xx-family SCSI (ncr, NCR825 Doesn't always work) .El .It Miscellaneous Devices .Bl -hyphen -compact Cyclades Cyclom-Y serial boards (cy, UNTESTED) .It 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) .El .El .It ISA Bus .Bl -bullet -compact .It Network Cards .Bl -hyphen -compact .It 3Com 3c509 Ethernet (ep) .It DEC DE200,DE201,DE202 (le) .It DEC DE203,DE204,DE205 (lc) .El .It Miscellaneous Devices .Bl -hyphen -compact .It PC-style parallel ports (lpt) .It NS16450 and NS16550 UARTs (com) .It ISA multi-port 16x50 boards (such as ast, boca--only boca has been tested) .El .El .It EISA Bus .Bl -bullet -compact .It Network Cards .Bl -hyphen -compact .It DEC DEFEA FDDI (fea) .It 3Com 3c5xx series (ed, UNTESTED) .El .It SCSI Controllers .Bl -hyphen -compact .It Adaptec 274x and aic7770 SCSI (ahc, UNTESTED) .It BusLogic 7xx SCSI (bha, UNTESTED) .El .El .It Turbochannel Bus .Bl -bullet -compact .It Graphics Adapters .Bl -hyphen -compact .It CFB video (PMAG-BA, cfb) .It SFB video (PMAGB-BA, sfb) .El .(Note 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. .Note) .It Network Cards .Bl -hyphen -compact .It DEC LANCE Ethernet (PMAD-AA, le, UNTESTED) .It DEC DEFTA FDDI (PMAF-F, fta) .El .El .El .(Note 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) .(Note Note that some devices, especially ISA-based devices, have to have certain settings set properly for the install and GENERIC kernels to detect them.
