 I was wrong - I do have a MBR:
 
 Disk: /dev/rwd0
 NetBSD disklabel disk geometry:
 cylinders: 15538, heads: 16, sectors/track: 63 (1008 sectors/cylinder)
 total sectors: 15662304, bytes/sector: 512
 
 BIOS disk geometry:
 cylinders: 975, heads: 255, sectors/track: 63 (16065 sectors/cylinder)
 total sectors: 15662304
 
 Partitions aligned to 16065 sector boundaries, offset 63
 
 Partition table:
 0: NetBSD (sysid 169)
     start 64, size 15662240 (7648 MB, Cyls 0/1/2-974/237/63), Active
         PBR is not bootable: Bad magic number (0xaed4)
 1: <UNUSED>
 2: <UNUSED>
 3: <UNUSED>
 First active partition: 0
 Drive serial number: 0 (0x00000000)
 
 
 and disklabel agrees (wd0c == MBR partition 0):
 
 4 partitions:
 #        size    offset     fstype [fsize bsize cpg/sgs]
  a:  15137952        64     4.2BSD      0     0     0  # (Cyl.      0*-    942*)
  b:    524256  15138048       swap                     # (Cyl.    942*-    974*)
  c:  15662240        64     unused      0     0        # (Cyl.      0*-    974*)
  d:  15662304         0     unused      0     0        # (Cyl.      0 -    974*)
 
 
 ... but I don't get any message from the MBR bootsector:
 
 DiskSize: 3724132352Byte

 Set Transfer Mode result: 50 
 > b

 So apparently I don't have /usr/mdec/mbr installed and that is why I
 needed to use the raw partition (starting at the first sector) for
 installboot. I must have missed a step in the install docs.
