Second PCI card no detected in Windows
I'm using dual monitor system using my onboard VGA and a PCI S3 VGA Card. In BIOS, I set the PCI VGA Card as a primary VGA, and the setup work. I can use both of my monitor flawlessly.
The problem is when I set my onboard VGA as primary monitor, windows cannot detected my PCI VGA Card, and dua monitor wont work. In the device manager the S3 virge card had a (!) mark beside the icon.
I don't think this is a driver problem because it only happened when I set the primary VGA Card to the onboard VGA. The S3 driver is automatically installed by windows when I use the S3 PCI card as primary VGA.
Can anyone help me to solve the problem? Thank you.
