$NetBSD: README,v 1.10 1996/07/09 22:08:28 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 you 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. Chris Demetriou cgd@cs.cmu.edu
