In almost 90 % of the cases, the Marvell Miniport driver is found on the support CD for the motherboard you have in your computer. Insert the CD into the CD/DVD-rom and then you should be able to install the driver. Additionally, use another computer to download driver. You will need to know the motherboard model and brand. Remove the protecting cover from the case, and read the version of the motherboard then paste it on Google and download the network driver. Remember, the download process needs to be done on another computer.
