      1 mvme68k machines usually need little or no preparation before installing
      2 NetBSD, other than the usual, well advised precaution of BACKING UP
      3 ALL DATA on any attached storage devices.
      4 
      5 The following instructions should make your machine "NetBSD Ready".
      6 
      7 Power-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 
     15 Make sure the value for "stop" looks ok (if you've got 8MB you should
     16 have 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 
     24 Note that NetBSD bases it's year at 1968, and adds the year offset in
     25 the VME147's real-time clock to get the current year. So the '29' here
     26 equates to 1997. You may have to adjust your clock using the 'set'
     27 command 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,
     29 Motorola have acknowledged a year 2000 bug whereby the day of the week
     30 doesn't get set correctly by the 147Bug PROM. IT DOES NOT AFFECT NETBSD!)
     31 
     32 Also make sure that your VME147's ethernet address is initialised to
     33 the correct value. You'll find the address on a label on the inside of
     34 the board's front panel. Enter the last five digits of the address
     35 using the 'lsad' command.
     36 
     37 To install successfully to a local SCSI disk, you need to ensure that
     38 147Bug is aware of what targets are connected to the SCSI bus. This
     39 can be done by issueing the following command:
     40 
     41 -->     147-Bug> iot;t
     42 
     43 At this point, 147Bug will scan for any attached SCSI devices. After
     44 a short delay, a list of SCSI devices will be displayed. You will be
     45 asked if Bug should assign LUNs to SCSI ids, to which you should
     46 answer Y. You should also answer Y when asked if the information is
     47 to be saved to NVRAM.
     48 
     49 The following installation instructions will assume that your target
     50 SCSI disk drive appears at SCSI-id 0. If you have a tape drive, the
     51 instructions assume is is configured for SCSI-id 5. When the RAMDISK
     52 root boots, NetBSD will refer to these devices as 'sd0' and 'rst0'
     53 respectively. You may wish to note these down; you'll be using them
     54 a lot. :-)
