Hard Disk Interface
ATA Full Name Advanced Technology attachment, is the traditional 40-pin and port data cable connection between the motherboard and the hard disk, the maximum external interface speed of 133mb/s, because the same line of interference is too poor, and line space, adverse computer cooling, will gradually be Replaced by SATA.

SATA is the abbreviation for Serial ATA, Serial ATA. This is a new type of hard disk interface that is completely different from parallel ATA, and is named because it transmits data in a serial way. SATA bus using embedded clock signal, with a stronger ability to error correction, compared with the past, the biggest difference is that the transmission instruction

Technology Attachment (ATA ). when the IDE standard was first introduced, many motherboards required separate controller cards to interface with IDE devices.
Almost all modern motherboards have two on-board ide ports, with each port being able to control two ide devices, for a total of four. if you want to add more than four ide devices, you must install an additional controller card such as the one shown in Figure. IDE ports have 39 or 40 pins and
(BiOS bootstrap loader) service. Common devices are as follows:First Floppy Drive, first ATA Hard Drive, pci ata card drive, atapi CD-ROM drive, PCMCIA controller bootable card, Ethernet controller code embedded in BIOS
PNP cards:This type of IPL device must be attached to the option Rom in the C0000h-EFFFFh (2 k boundary ). In addition, the option Rom must contain the PNP option Rom header (table 2 ). I
Our computer has been working for a whole year, and it is also strange and hard, especially the hard disk brother undertakes an important task of data storage. This is not the case. We can take advantage of this rare idle time to optimize the hard disk. It is not only a matter of improving the hard disk's work efficiency and extending its service life, but also a matter of pity.Below, I will introduce the hard disk optimization settings in two major aspects:I. BIOS Optimization

Installed many times the machine, various operating systems, this time in the WIN8 system has encountered some problems, now summarized as follows.The lab teacher gave a new Dell machine, the original is the WIN8 operating system, very inconvenient, do not want to make this system off, so you want to install a win7, that is, dual operating system. This Dell machine, F2 is BIOS,F12, is the boot entry for the system.The initial phase of the installation system found that the system's hard drive wa
I failed to verify the problem I had struggled with several times. Today I finally found the answer. The impression is that parallel technology is better than serial technology, but we can see that Sata is more difficult than pata !!

What are SATA and PATA? Both are ata standard hard disks.

have built-in RAID features or has been in the BIOS to turn off RAID features, you can not load the driver, directly install the system.
Scenario four: Some motherboards from the IDE to the SATA transition period, SATA is turned off by default in the BIOS. You need to manually enable the line.
SATA interface: Serial ATA (SATA, serial Advanced Technology attachment), also known as Serial ATA, is the twin
following mainly analyzes the bfin_bmdma_setup and bfin_bmdma_start functions, namely the DMA Operation Process:
(1) The software has prepared a PRD table in the memory, each 8 bytes, aligned to the 4-byte boundary.
(2) The software sets the start address of the PRD table, and sets the data and transmission direction by setting the read/write control bit to clear the interrupt bit and error bit in the Status Register.
(3) The software sends the DMA instruction to the disk device.
(4) Write 1 to
capacity is smaller, so when you design the BIOS, when converting addressing addresses from address registers of INT 13 to an IDE (ATA) address register, only the 10-bit address in the INT13 corresponds to the 16-bit cylindrical registers in the IDE (ATA) interface, and the not-used 6-bit ( High register) address is set to 0. At the same time, only the 6-bit sector address corresponds to the 8-bit sector r
