What does it mean that the Marvell 91xx SATA 6G Controller device won't boot?

It should be a chip problem, you can replace Marvell9128 PCI-Express to 2-port SATA6G (SATA III) array card.

SATA: Serial ATA (SATA, Serial Advanced Technology Attachment), also known as Serial ATA, is the twin brother of Serial SCSI (SAS: Serial Attached SCSI), and the two are compatible with each other in terms of wiring, and a SATA hard disk can be connected to a SAS interface. SATA hard disk can be connected to the SAS interface. It is a computer bus whose main function is to transfer data between the motherboard and a large number of storage devices (such as hard disks and CD-ROM drives). Serial interfaces also have the advantage of simple construction and support for hot-plugging. Here it is necessary to explain the data transfer rate of Serial ATA. In the context of serial communications, the data rate refers to the actual bit rate at which data is transmitted over the serial interface, which is 1.5 Gbps for Serial ATA 1.0 and 3.0 Gbps for Serial ATA 2.0. Like other high-speed serial interfaces, the Serial ATA interface employs a coding mechanism that ensures the characteristics of the data stream. This encoding mechanism encodes the original 8 bits of data per byte (i.e., 1Byte = 8bit) into 10 bits of data (i.e., 1Byte = 10bit), so that each byte of serial data stream of the Serial ATA interface contains 10 bits of data, and the encoded Serial ATA transfer rate is correspondingly one-tenth of the actual transfer rate of Serial ATA. , so 1.5Gbps = 150MB/sec and 3.0Gbps = 300MB/sec.?
