Installation guide

Bull S.A. May 25th, 1999
Estrella Series 200 only:
• When one or several PCI graphics boards are plugged, you can have difficulties to
continue to use the planar graphics subsystem (the Cirrus controller): refer to
/usr/lpp/X11/README.
• If 3 PCI graphics boards are plugged, the planar graphics subsystem must not be used in
the same time.
Modify the file /usr/lpp/X11/defaults/xserverrc in setting the variable
EXTENSIONS with the standard AIX Server –P gga<n> flags for each graphic adapter.
See the X Server start–up flags for more information about the –P gga<n> flag.
• It is not possible to test the graphics controller on the mother board (cvga0) by
PPC1–Diag (VGA543X) if a PCI graphics adapter is plugged in.
As soon as the PCI adapter has been unplugged, PPC1–Diag runs fine.
• There is no possibility under PPC1.bug to detect the available graphic RAM. When you
configure the resolution display 1280x1024 60Hz, you must use xdpyinfo to know the
exact graphic configuration.
