SYMPTOMS
An extra display adapter (SiS 5597/5598) appears in the "Device Manager." The modem will not install properly to COM2.
CAUSE
The on-board VGA option is not disabled.
RESOLUTION
Some of PCs come with a graphics card installed (in addition to the on-board video). The on-board VGA must be set to "Disabled." Follow the steps below to disable the on-board VGA. You will need to refer to the motherboard manual included with your PC for assistance with these steps.
- Shut Down the computer and remove the power cord.
- Remove the PC's case cover.
- Locate the tiny set of pins labeled "JP23."
- Cover pins "2" and "3" of "JP23" with the small piece of plastic (or jumper), located on the pins.
- Locate the tiny set of pins labeled "JP24."
- Cover pins "1" and "2" with the plastic jumper.
- Locate the tiny set of pins labeled "JP25."
- Cover pins "2" and "3" with the plastic jumper.
- Verify that the VGA Connector cable is not connected and is removed from the PC.
- Replace the PC's case cover and return the power cord to the back of the PC.
- Power on the computer.
The extra display adapter should disappear and the modem should automatically configure to COM2.
