When the PG 740 is powered up, the system automatically recognizes the
additional graphics card. The display and the built-in VGA graphics interface
module are switched off. To switch the display and the built-in VGA graphics
interface module back on, proceed as follows:
1. Switch on the PG 740.
2. While the PG 740 is being powered up, keep the INSERT key depressed
until you hear two signal tones.
The additional graphics card is reactivated the next time you switch the
PG 740 on without pressing the INSERT key.
You can connect both a PS/2 and a serial mouse to the PG 740. The PG 740
is delivered with the mouse driver for the trackball and PS/2 mouse already
loaded.
You can connect an external PS/2 mouse or another external pointing device
to an additional PS/2-compatible mouse connector.
