+ <p>NetBSD/netwinder is now installed on the disk image. But actually

+ <p>Something like the following command line would be used to start

+ </pre>
+ <p>Note: The installation instructions above create a filesystem
+ <i>without</i> a disklabel, so there is only one ffs partition and no
+ swap. You will need to enter the following things when booting with the
+ generic kernel:<pre>
+         root device (default wd0a): <b>wd0c</b>
+         dump device (default wd0b): <b>none</b>
+         file system (default generic):    <i>(just press enter)</i>
