3mvme68k machines usually need little or no preparation before installing
4NetBSD, other than the usual, well advised precaution of BACKING UP
5ALL DATA on any attached storage devices.
6
7The following instructions should make your machine "NetBSD Ready".
8
9Power-up your VME147. You should have the "bug" prompt:
10
11        COLD Start
12
13        Onboard  RAM start = $00000000,  stop = $007FFFFF
14
15        147-Bug>
16
17Make sure the value for "stop" looks ok (if you've got 8MB you should
18have the same value as I do). Also make sure the clock is ticking:
19
20        147-Bug>time
21        Sunday   12/21/29   16:25:14
22        147-Bug>time
23        Sunday   12/21/29   16:25:15
24        147-Bug>
25
26Note that NetBSD bases it's year at 1968, and adds the year offset in
27the VME147's real-time clock to get the current year. So the '29' here
28equates to 1997. You may have to adjust your clock using the 'set'
29command to comply with NetBSD's requirements. Don't worry if the
30"Day of the week" is not correct, NetBSD doesn't use it. (Actually,
31Motorola have acknowledged a year 2000 bug whereby the day of the week
32doesn't get set correctly by the 147Bug PROM. IT DOES NOT AFFECT NETBSD!)
33
34Also make sure that your VME147's ethernet address is initialised to
35the correct value. You'll find the address on a label on the inside of
36the board's front panel. Enter the last five digits of the address
37using the 'lsad' command.
38
39To install successfully to a local SCSI disk, you need to ensure that
40147Bug is aware of what targets are connected to the SCSI bus. This
41can be done by issueing the following command:
42
43-->     147-Bug> iot;t
44
45At this point, 147Bug will scan for any attached SCSI devices. After
46a short delay, a list of SCSI devices will be displayed. You will be
47asked if Bug should assign LUNs to SCSI ids, to which you should
48answer Y. You should also answer Y when asked if the information is
49to be saved to NVRAM.
50
51The following installation instructions will assume that your target
52SCSI disk drive appears at SCSI-id 0. If you have a tape drive, the
53instructions assume is is configured for SCSI-id 5. When the RAMDISK
54root boots, NetBSD will refer to these devices as 'sd0' and 'rst0'
55respectively. You may wish to note these down; you'll be using them
56a lot. :-)
