Hi, everyone.

 I use NetBSD/pmax(1.2_Beta) on DEC Station 3100(color model,
memory 24MB, rz0(280MB/FUJI), rz1(280MB/FUJI)).
NetBSD/pmax is able to execute ultrix binaries under the kernel
configured "option ULTIRIX_COMPAT".
 I have made X11R6 on NetBSD/pmax, but can't make Xdec because of
lack of ultrix oriented header files and incompatibility between
gas and ultrix as (xc/programs/Xserver/cfb/stipmips.s) and so on.
 I get
  ftp.netbsd.org:/pub/NetBSD/arch/pmax/ports/x11r6-clients.tar.gz
and extract into my machine, and put Xdec(X11R6) which is made
under Ultrix 4.3 environment into /usr/X11R6/bin. Some ultrix
binaries are reqired "/etc/svc.conf" then I put it from ultrix
machine. Xdec use "/dev/mouse", then hard link from "/dev/pm0".

 I execute "startx" or "xinit", then system is panic.

 How can I use Xdec for ultrix 4.3 on NetBSD/pmax ? and How can I
get these panic trap message into file ?

Thank you in advance.
