$NetBSD: README,v 1.8.4.1 1996/06/13 20:49:01 cgd Exp $
Obtaining NetBSD/Alpha sources and binaries:
NetBSD/Alpha's sources, with the exceptions of the GNU
toolchain and X11 code, are integrated into NetBSD-current,
and are available from:
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/
The latest NetBSD/Alpha binary snapshot, and source snapshots
for the toolchain and X11 code, can be found at:
ftp://ftp.netbsd.org/pub/NetBSD/arch/alpha
Binary snapshots include two different set of system binaries:
(1) an rz25 disk image, for first-time installation
(see below for instructions), and
(2) three tar files of the binaries, for updates.
(one of the tar files is the contents of /etc,
one contains X11 binaries, and the last is everything
else, except the kernel and the installed boot block.)
There are no instructions on how to use these.
Good luck! 8-)
Binary snapshots include a kernel image which is the same
as the one on the rz25 disk image.
The sources provided seperately from the normal NetBSD-current
distribution are:
(1) complete compiler toolchain sources
(2) diffs against the XFree86 3.1.2 distribution to
make X work with NetBSD/Alpha. (Note that
at this time, the diffs are against 3.1.2,
i.e. not against 3.1.2D, etc.)
If you are using or are interested in the NetBSD/Alpha port, I
suggest that you subscribe to the NetBSD "port-alpha" mailing list
by sending an email message to majordomo@netbsd.org with no
subject and with a body of "subscribe port-alpha" (without the
quotes). For help on using majordomo, send it mail with an empty
subject and body. In general, questions about NetBSD/Alpha
are best asked on that mailing list (rather than by sending me
mail directly).
Installing the NetBSD/Alpha distribution:
[ Note that these instructions are minimal; it's assumed that if
you're going to be installing this, you're knowledgeable about
booting Alphas and doing sysadmin-ish stuff, are willing to look
in your Alpha documentation, or are brave. If they're really not
good enough to get you running, get in touch with me and I'll try
to help you. ]
To install the NetBSD/Alpha distribution, you'll need a disk at
least the size of an RZ25 -- about 406Mb. Once you've gotten the
binary distribution, gunzip it and dd it to the raw disk. The binary
distribution includes a disklabel and boot block, so you don't need
to do anything special to make it bootable. The binary distribution's
file systems are created with an older version ("Level 1") of the
Berkeley Fast File System format, so that you can mount, read, and
write them under Digital UNIX.
If your are using one of the supported systems that includes a
PCI bus, and have either a PCI VGA frame buffer of any type or
a ZLXp-E1 frame buffer, you may use it as console. (If you
are using your frame buffer as the console, you should use the
terminal type 'sun'.) Otherwise (if you are using a TurboChannel
Alpha or have a different kind of frame buffer, you have to use
a serial console.)
Boot the Alpha with the NetBSD disk, supplying the boot flag "-s".
It should print something like "NetBSD/Alpha Boot program", load
the kernel, print a copyright, and print various startup messages.
After a short while, you should be asked for the name of a shell
to use; just hit return. You're advised to fsck the disk at this
point (the root partition is partition 'a' and the /usr partition
is partition 'd'), remount the root partition read-write (use mount
-u root-dev /), and create some necessary system information files:
/etc/hosts
/etc/resolv.conf
DNS resolver configuration information, if you
want to use DNS.
/etc/myname
The hostname of the machine.
/etc/mygate
The LAN's gateway's IP address, if your network
setup requires that a static route to the
gateway be created.
/etc/hostname.xxy
(where "xxy" is your machine's ethernet
interface name, e.g. "le0" for TurboChannel
machines or "de0" for PCI machines.)
The IP address, etc., for the named network
interface. (You can have multiple of these
files, for example, if the machine is
multi-homed.) The format can be discerned by
looking in /etc/netstart, and is typically
something like:
inet hostname.in.etc.hosts net.mask broadcast.addr
where the netmask is formatted as a hex number
(e.g. 0xffffff00), and the broadcast address
is formatted as an IP address (e.g. 128.2.255.255)
/etc/fstab
The file system information table for the system.
A prototype is in /etc/fstab.sd.
(You can also create the files mentioned above by mounting the
disk's file systems under Digital UNIX.)
Once those files are created, you should be able to boot the system
multi-user. To do so, halt the system and boot again from the
NetBSD disk, this time supplying the boot flag "-a".
If you used a disk other than an RZ25, you may want to edit the
disk's disklabel, and create one or more partitions after the
existing partitions to use the extra space.
