Today, Hikvision ’s vision controller needs to be reinstalled. The model is MV-VB2210-120G. What is the shortcut key to enter the BIOS?
I tried all the way from F1 to F7, and finally found it. Press the F7 key to enter the BIOS of the Haikang MV-VB2210 vision controller, and then select USB to start, you can install the ubuntu system from the USB flash drive.
