To install a dual-screen upgrade:
1. Shut down the system and turn off system power.
2. Disconnect the cable from the Video port on the back of the system base unit.
3. Open the system base unit as required to gain access to the PCI option board slots. Slots
are identified in “Connecting the Video Cables” later in this chapter.
4. Use a quarter-inch nutdriver to remove the blanking plates from PCI slots 1 and 2. Retain
the screws.
5. Install the new Z13, Z25, or V25 board in PCI slots 1 and 2.
In a dual-screen configuration, the primary and secondary Z13, Z25, and V25 graphics
accelerators are determined as follows:
Primary: Board installed in PCI slots 1 and 2
Secondary: Board installed in PCI slots 3 and 4
6. Install the screws that were previously removed to secure the board to the system chassis.
7. If a Geometry Accelerator board is installed, connect the dual-screen Vertex data bus
between it and the graphics boards. The following figure shows two Z13, Z25, or V25
boards.
NOTE
The connectors of the dual-screen Vertex data bus can be installed in only one orientation.
8. Install the clock sync cable between the two Z13, Z25, or V25 boards shown in the
previous figure.
