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