To boot the system via USB on Advantech 610L ICPC, you can set it up as follows:
Insert a USB flash drive: Insert a bootable USB flash drive you have prepared into one of the available USB ports on the ICPC.
Enter BIOS setup: Reboot the ICPC and press the DEL key (or maybe F2, F10, F12, etc.) to enter the BIOS setup during bootup.
Setting boot sequence: In BIOS setup, find the "Boot" tab, enter it, select "Boot Option #1" (or similar option), and set it to USB flash drive (you may need to use the arrow keys and Enter to select and confirm). If you want to use a USB flash drive as the preferred option, then select "Boot Option #1" (or similar). If you want to use a USB flash drive as your preferred boot device, you can set the option for other boot devices to "Disabled".
Save Settings: After completing the settings, follow the interface prompts to select "Save Changes and Exit", and then press Enter to reboot the PC.
System startup: When the ICPC starts up, it should first try to boot from the USB flash drive, and if there is a bootable operating system on the USB flash drive, the system will boot from the USB flash drive.
Precautions:
When performing BIOS setup, please be careful not to change other unfamiliar options that may cause abnormal system startup or other problems.
Make sure that a bootable operating system exists on the USB flash drive, otherwise the ICPC will not be able to boot from the USB flash drive.
During startup, some ICPCs require you to press F12 or other keys to select the boot device, if you are unable to boot from the USB flash drive, try pressing other keys to select the boot device.
