The SATA interface mode of PCIE to SATA3.0 is AHCI mode. If you want to insert a system disk on our card, the premise is that your system disk must be installed in AHCI mode when installing the system on the motherboard, otherwise it will not pass Our card riser starts the system.
If it is determined that the system disk is inserted into the SATA interface on the motherboard and the installation system is in AHCI mode, then you can directly insert the hard disk into our card, and then enter the motherboard BIOS to set the system disk as the first boot.
The above two conditions are met. If it still fails to start, or restarts repeatedly, it may be because the hard disk interface of the motherboard conflicts with our adapter card. The solution is to enter the motherboard BIOS and set the hard disk interface option of the motherboard to Disabled, save and restart to start the system
When the system disk is inserted into the motherboard, and the ordinary disk is inserted into the PCIE to SATA3.0 card, it is only necessary to detect the information of the riser card and the model of the ordinary disk during startup.
If the condition 1 is established, the system still cannot be started, then you need to enter the motherboard BIOS and set the system disk as the first startup.
