Intel 82801 refers to the Southbridge chip, of the motherboard chipset;
for an Intel 800 series motherboard chipset, for the Intel Pentium 4 series processors,
http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsetsNotice in the chart under the heading - South bridge;
ICH2, and ICH4 and ICH5 and ICH5R
http://en.wikipedia.org/wiki/List_of_intel_chipsets#Southbridge_8xx_chipsetsDoes NOT state anything exact about the motherboard.
For this you need the Model Number.
Granted the Southbridge chip, of the motherboard chipset; is what handles the Slower capabilities of a computer.
Audio is one,
http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg[Note CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Does NOT mean personal Computer.
This technology applies to YOUR motherboard, and not to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9, processors ]
However the Southbridge chip handles Audio through the Audio chipset.
Driver: Small piece of software that allows the Operating System to communicate with a device
The device is the Audio chipset.
You didn't state what Windows O/S you are using.
The reason BIOS doesn't detect the Audio chipset, is because the Driver is gone. Audio driver.
(Windblows lost the address to the driver)
IF, I have the model number of the motherboard;
Or,
IF I have the manufacturer name of the computer, and it's model number;
I can look to see if Audio drivers are available, and instruct you how to download, AND install.
I also need the Operating System used.
Windows what?
