Hi Christoph,

Thanks for the pointer. I looked on a mirror and on the master server,  
and I don't see any ISO images for current:

ncftp /pub/NetBSD/iso > pwd
  ftp://iso.NetBSD.org/pub/NetBSD/iso/
ncftp /pub/NetBSD/iso > dir
d------r-x                Nov  3  2006   3.0.2
d------r-x                Apr 20  2007   3.1
d------r-x                Jan 29  2008   4.0
d------r-x                Oct 12 13:11   4.0.1
d------r-x                Nov 12  2006   livecd

Is it in a different path on the FTP server?

Thanks,
        -Andy.
