If it is determined that the system disk is inserted in the AHCI mode of the SATA interface mounting system on the mainboard, then the hard disk can be directly inserted into our card, and then the mainboard BIOS is set to start the system disk as the first boot. 3, the above two conditions are available, if you still can not start, or repeatedly restart, then the motherboard hard drive interface and our adapter card conflict, the solution is to enter the motherboard BIOS, the motherboard's hard disk interface options set to Disabled, save and restart to boot the system description material: metal Colour: Black Support Interface: USB3.0 TO SATA 22PIN Support System: WinXP/Vista/Win7/Win8 32-bit/64-bit LINUX Meets Serial ATA 3.0 specification, backward compatible with SATA2.0 SATA1.0 Compliant with PCI-Express v2.0 specification, backward compatible with PCI-Express v1.0.
