To check the settings in your BIOS probably look under Advanced chipset features, PNP/PCI configurations, or the last place to look would be in Integrated Peripherals. Some BIOS setting are in different locations within the BIOS. Check each location til you come across the right area. Sorry I can not be of further assistance to you.
As far as updating your chipset drivers, you can find them on the motherboard manufacturer's website. Look under drivers and downloads when you find the motherboard model number. They should have any and all updated drivers for your computer.
