I gave up on booting from disk and setup diskless boot from a NetBSD
server. Now it says:

0 > boot enet file: 192.168.0.68,ofwboot.xcfloading XCOFF
tsize=C1C0 dsize=1500 bsize=1608 entry=600000
SECTIONS:
.text    00600000 00600000 0000C1C0 000000E0
.data    0060D000 0060D000 00001500 0000C2A0
.bss     0060E500 0060E500 00001608 00000000
loading .text, done..
loading .dataCLAIM failed
 ok

Any more ideas?
