This document is an expert user's guide to Unix on the Alpha PC. It explains

how to plug the machine together, and how to boot it the first time. It expects

that expert users can deal with changing the password file, the default file

systems file, the network configuration files, and so on, without help.

Unpacking

You should receive:

1) An Alpha PC system unit, with its line cord. Unless you have heard otherwise from us, the system unit contains an

EV4 CPU chip, 32 megabytes of memory, a Western Digital WD8013 (16 bit) Ethernet adaptor, an ATI 8514-Ultra

display adaptor, an Adaptec AHA-1522 SCSI disk controller, and a DEC RZ25 disk pre-loaded with software. You will

also get a console key, which fits in the keylock on the front of the box.

2) A BCT-5339 101 key keyboard.

3) A Logitech 3 button mouse.

4) A keyboard/mouse adaptor cable. This is a short cable (about a foot long) with a 7 pin connector on one end (which

plugs into the system unit) and a black piece of plastic that looks like a torpedo on the other end. If you look closely at

the torpedo you will see that it has a a keyboard connector on one side and a mouse connector on the other side.

5) A DEC VRT13 VGA display, with it's video cable and line cord, unless you are not in North America, in which case

you will use your own monitor, since we have no 220 volt compatible monitors.

Plugging Everything Together

Everything goes together as you expect.

The system unit's line cord goes into the wall. If you are not in North America you should take the cover off the box

(single screw on the back, top center) and check that the line voltage selector switch on the side of the power supply is

in the 220 volt position (we try to remember to switch these, but we do forget sometimes).

The monitor's line cord goes into the wall. The monitor video cable goes between the monitor and the 15 pin D-sub on

the back of the display card.

The Ethernet plugs onto the BNC on the back of the Ethernet card. The card is configured for thinwire. If you want to

use thickwire you can do so by taking the cover off the box, removing the Ethernet card, and moving the XXX stake

pins on the card (we've never done this; if you try it and it works, tell us).

The keyboard and the mouse plug into the adaptor cable, and the adaptor cable plugs into the system unit. The

mouse connector will not go in as far as you might expect, because Logitech changed the connector and it isn't quite

the same as the socket on the adaptor cable, but if you push it in as far as it will go everything is fine.

If you want to connect a serial console to the machine, the terminal should be set to 9600 baud, and plugged into

serial port A, which is the 9 pin D-sub closest to the edge of the box.

Booting

You should first try booting from the serial console. Set the keyswitch on the front of the machine to the locked

position, and turn the machine on. The boot roms should display the date they were made, and prompt for input. Type

the commands to fill memory with zeros, load the system image from the disk, and jump to it.

Beta EPROM: Thu Dec 19 18:57:14 EST 1991

(bdu) fill 20000 780000 0

(bdu) fill 800000 2000000 0

(bdu) scsiboot 2 vmunix.4

(bdu) jtopal 20000

The "4" on the end of "vmunix.4" indicates that this is an EV4 image. If you know that your Alpha PC has an EV3 in it

instead, you should use "vmunix.3" instead. The "vmunix.4" image assumes that the chip has a floating point unit, so it

will die a horrible death if you run it on an EV3.

Unix will come up, and you'll get a single user prompt. At this point you should check the file systems. If fsck

announces that you should HALT PROCESSOR WITHOUT SYNCING DISK you should just hit the reset button on

the front panel and start everything over. Eventually you will get the filesystems clean, and you can type "^D" to bring

the system the rest of the way up.
