is not a motherboard model number, it's a chipset that was used on hundreds of motherboards including some made by Asrock. You need to provide the actual Asrock motherboard model if you expect anyone to help.
If you're unable to do so, then I suggest using this program:
To find make and model of pc hardware, EVEREST Home Edition
is a free system diagnostics, system information program that will id
most hardware onboard a mb. as well as the actual motherboard. It will, in some cases, actually provide a download link for the driver.
Alternate Everest download link: (offers 2 sites to dl program from)
Run the program and then:
Click on Computer
Click on Summary
Right hand window (hardware) if the text is BLUE
this is a link to the web site for that particular hardware.
If you have additional questions or need further help, please post a "copy and paste" of the COMPUTER SUMMARY report (Leave out the Debug –PCI section) from Everest.
Or you can visit the Asrock driver page
to see if you can match your unknown motherboard with one of the valid model numbers they have listed.
