For a friend who has never used a USB add-in, it is possible that the system cannot detect a USB hard drive even if the driver is properly installed, mainly because the default CMOS port on the moth
Linux boot-up process analysisthe boot process refers to the entire process from powering on the computer until Linux displays the user login screen. Analyzing the Linux boot process is also a great way to get an insight into the workings of the Linux core.

If you have five PCI slots on your motherboard, when you use more than two PCI devices, try not to use the PCI1 slots to avoid conflicts. When you add a new device, you should also read the specification of the device in detail.

To solve this problem, we can reboot, enter the CMOS Setup window, and in the "Pnp/pci CONFIGURATION" column, "Assign IRQ for USB" is set to "Enable", This allows the system to assign an available interrupt address to the USB port.
