This chapter describes how you can configure your system using a TurboGXplus card to suit your specific video/graphics requirements. The information describes how to set up your TurboGXplus to support different screen resolutions and how to set up the system to support multiple monitors.
Table 1-1 shows the list of monitors supported by the TurboGXplus card.

Resolutions in bold type are the default resolution at power-on initialization.
* Monitor ID sense code is user-selectable by switch on rear.

Nvramrc is a nonvolatile PROM script memory. When the PROM reaches the
device probing stage, it checks the variable
The following code places resolution initialization between the probe-sbus stage and the install-console and banner stages. First probe-sbus is called to probe all devices, so that the device tree is created, and the devices are initialized.
The next line defines a Forth word called

The line,
The next line, pushes the string /sbus/cgsix@1 onto the Forth stack, the path for the device where the resolution is to be changed.
The following example changes the cgsix frame buffer on SBus slot 1. The
string "override" is the actual entry point in the cgsix fcode PROM which
reconfigures the resolution from the data present on the forth stack. execute-
