prep revision 1.1 
1mvme68k machines usually need little or no preparation before installing
2NetBSD, other than the usual, well advised precaution of BACKING UP
3ALL DATA on any attached storage devices.

5The following instructions should make your machine "NetBSD Ready".
6
7Power-up your VME147. You should have the "bug" prompt:
8
9        COLD Start
10
11        Onboard  RAM start = $00000000,  stop = $007FFFFF
12
13        147-Bug>
14
15Make sure the value for "stop" looks ok (if you've got 8MB you should
16have the same value as I do). Also make sure the clock is ticking:
17
18        147-Bug>time
19        Sunday   12/21/29   16:25:14
20        147-Bug>time
21        Sunday   12/21/29   16:25:15
22        147-Bug>
23
24Note that NetBSD bases it's year at 1968, and adds the year offset in
25the VME147's real-time clock to get the current year. So the '29' here
26equates to 1997. You may have to adjust your clock using the 'set'
27command to comply with NetBSD's requirements. Don't worry if the
28"Day of the week" is not correct, NetBSD doesn't use it. (Actually,
29Motorola have acknowledged a year 2000 bug whereby the day of the week
30doesn't get set correctly by the 147Bug PROM. IT DOES NOT AFFECT NETBSD!)
31
32Also make sure that your VME147's ethernet address is initialised to
33the correct value. You'll find the address on a label on the inside of
34the board's front panel. Enter the last five digits of the address
35using the 'lsad' command.
36
37To install successfully to a local SCSI disk, you need to ensure that
38147Bug is aware of what targets are connected to the SCSI bus. This
39can be done by issueing the following command:
40
41-->     147-Bug> iot;t
42
43At this point, 147Bug will scan for any attached SCSI devices. After
44a short delay, a list of SCSI devices will be displayed. You will be
45asked if Bug should assign LUNs to SCSI ids, to which you should
46answer Y. You should also answer Y when asked if the information is
47to be saved to NVRAM.
48
49The following installation instructions will assume that your target
50SCSI disk drive appears at SCSI-id 0. If you have a tape drive, the
51instructions assume is is configured for SCSI-id 5. When the RAMDISK
52root boots, NetBSD will refer to these devices as 'sd0' and 'rst0'
53respectively. You may wish to note these down; you'll be using them
54a lot. :-)
