I didn't write this technique. I saw it on the Internet. Simply translate it.

Tianyi 510S-08IKL Desktop installation operating system USB can not solve the solution LENOVO Desktop

Machine name: Tianyi 510S-08IKL

Machine number: M703LBP5

Solution that cannot be used by USB after installing win7 in Tianyi 510pro

Recently, the company received an order of business, and customers entrusted us to buy a batch of contact Tianyi 510pro desktops. The machine is factory-installed with windows10, but customers are required to install win7 64-bit due to software limitations.

Several technologies have installed win7 64-bit in the previous way, and all USB cannot be used. Finally, feedback to me, I would like to share with you today my treatment plan. I queried the configuration information of this machine on Lenovo's official website as follows:

Problem analysis:

From the configuration above, we know that the seventh generation processor is used; the chipset of Intel b250. The seventh-generation processor i3 uses Kaby Lake architecture, which will be the seventh-generation smart processor of Intel. Mass production will begin in June 2017. (Kaby Lake will add native USB 3.1 and HDCP 2.2.

Support, as well as full fixed function HEVC main10 and VP9 10-bit hardware decoding. Will be more efficient than Skylake). The seventh generation processor (Kaby Lake) architecture corresponds to Intel's chipset series motherboards such as H100 and B250, which fully uses the Usb3.0/3.1 interface of the Xchi technology standard, Win7.

There is no built-in driver in the system, and there is no native support for this technical standard. In the face of motherboards that are not equipped with USB2.0 and PS/2 interfaces at all, Win7 can't even use a keyboard and mouse. Therefore, it is believed that Win7.CeoMSX cannot be installed on the 100 series motherboard, and the disk control comes from the system bus.

(AHCI\ RAID) and USB3.0/3.1 driver import tools to support offline import of disk controller drivers and XHCI drivers

Solution:

The first thing to do is to make preparation tools.

1. PE tool CD-ROM or USB disk

2. Automatic answer file, no need to be on duty when the system is encapsulated

3. Win7 64 Ultimate Edition sp1 system Image

4. The most important thing is whether the driver file can be successful.

Step 1: modify BIOS settings

1. Change Secure Boot to Disabled and disable secure startup

2. Change CSM to Enable or Yes to indicate compatibility

3. Change Boot mode or UEFI mode to Legacy, indicating the traditional startup method.

4. Change OS Optimized Defaults to Disabled or Other OS, and disable the default system priority setting.

5. Some models need to set the BIOS password before you can modify Secure Boot. Find the Set Supervisor Password to set the password.

You need to modify the partition format after booting through PE

Then mount the system image and install the system, where "unattended" and "add drivers need to be checked", which is somewhat different from the previous direct installation system.

Attachment:

Unattended answer file and driver file (the driver file is omitted, the following is the contents of the answer file). If you are interested, you can download it yourself.
