Installation guide

– PowerStorm graphics card: SCREEN 1
For reference, the power connector is situated above the PCI slots, and the
CPU and ISA connectors below.
All PowerStorm cards must have the ALIAS jumper in and VGA EN jumper
out, except the SCREEN 0 card, which must be VGA enabled.
3.6.4.3 Software Setup
After you complete the hardware configuration for the eight-headed system,
you can set up the Tru64 UNIX software to operate the eight screens as one
row of eight screens (8x1) or two rows of four screens (4x2).
By default in a multiheaded configuration, the screens are operated as 8x1.
To set up the screens in a 4x2 combination, you must edit your system’sX
Window System server configuration file,
/usr/var/X11/Xserver.conf.
Instructions for editing this file in order to customize the X server
configuration are provided in the Xserver(1X) reference page.
To set up 4x2 operation, you need to specify –edge_top,
–edge_bottom, –edge_right, and –edge_left command-line
arguments that arrange and attach the screens as you want them. Each
argument takes scr1 and scr2 values, which are the numbers of the
screens you are attaching.
For example, you could arrange the eight screens as follows:
/---------------\
|4|5|6|7|
|---------------|
|0|1|2|3|
\---------------/
To achieve this combination, add the following information to the
command-line arguments section of Xserver.conf:
