3.4 Enabling USB Ports for Windows® 7 Installation Intel® new processors have removed their support for the Enhanced Host Controller Interface (EHCI - USB2.0) and only kept the eXtensible Host Controller Interface (XHCI - USB3.0). Due to that fact that XHCI is not included in the Windows 7 inbox drivers, users may find it difficult to install Windows 7 operating system because the USB ports on their motherboard won't work. In order for the USB ports to function properly, please create a Windows® 7 installation disk with the Intel® USB 3.0 eXtensible Host Controller (xHCI) drivers packed into the ISO file. Requirements • A Windows® 7 installation disk or USB drive • A Windows® PC • Win7 USB Patcher (included in the ASRock Support CD or downloaded from website) Scenarios You have an ODD and PS/2 ports: If there is an optical disc drive, PS/2 ports and PS/2 Keyboard or mouse on your computer, you can skip the instructions below and go ahead to install Windows® 7 OS. You've got nothing: If you do not have an optical disc drive, please find another computer and follow the instructions below to create a new ISO file with the "Win7 USB Patcher". Then use the new patched Windows® 7 installation USB drive to install Windows® 7 OS. 56 English
