SATA II is the chip giant Intel Intel and HDD giant Seagate Seagate developed on the basis of SATA, its main feature is that the external transmission rate from the SATA 150mb/s further increased to 300mb/s, in addition to the NCQ (Native Command Queuing, native command queue, Port multiplier, staggered start (staggered spin-up) and a series of technical features

Intel is planning to let H61 continue to use its residual heat in low-end markets. But H61 's shortcoming is too obvious, is the specification is too low, difficult to meet the user's need. As a result, many motherboard vendors B75 the entry-level commercial motherboard chipset to the consumer-level market. B75/B85 Motherboard Introduction B75 Motherboard The B75 is Intel's motherboard chipset for small and medium businesses and commercial users, and is much more powerful than a c

Recently, the server encountered a small problem. I had to redo raid. I found an article on the Internet. I felt very careful. I 'd like to share it with you. Record the record when the server is reinstalled and share it with you. Hardware RAID 5: Recently, I personally assembled a 1u rack-mounted storage server with an 8-hard drive using a dual-core P4 820d processor. During the assembly process, I created a disk array of hardware RAID 5 and software RAID 5 respectively, the process is very in

better than Windows NT + IIS to run ASP, while Apache is slightly more dominant. The existing version can process more than 10000 operations (one request is one operation) within one second on a high-performance host ). Therefore, enterprises select the appropriate software platform and hardware based on application development requirements. At present, computer development is very fast, and mainstream Xeon multi-core technologies can meet the needs of 0.1 million of users. At the same time,

[Host planning and disk partitioning] disk partitioning MBR and disk partitioning mbrRelationship between the disk connection method and the device file name The mainstream disk interfaces areSATA interface. SATA, USB, SCSI, and other disk interfaces are all driven by the SCSI module.Therefore, the disk device file names of these interfaces are/Dev/sd [a-p]Format. The order depends on the order in which the Linux kernel detects the disk. For example,

development of the network, storage is no longer confined to the inside of the computer shell, the network storage is becoming the mainstream in the server field. In the storage device is the most important should be hard disk, the drive to read and write speed, capacity and quality of the pursuit of hard disk technology has undergone several changes. From the interface standard of the motherboard with the ATA (IDE), SATA, SCSI, SAS, FC and InfiniBan

unpartitioned space for virtual machines.(9) for serial ATA (SATA), there is a disk that is connected by a supported SAS controller or a supported onboard SATA controller. The SATA disk will be considered a remote, non-local disk. By default, these disks are used as staging partitions because they are treated as remote disks.PS: The

the above method, the virtual hard disk named boot defaults to SDA, and the name of the virtual hard disk named Home is SDB. If you want to change, you can do this:Select Boot.vdi, click on the SATA Port drop-down list on the right, you can see the BOOT.VDI SATA port is the 0,HOME.VDI SATA port is 1, here you can set the BOOT.VDI

Symptom: the hard disk cannot be found when the system is installed on the Windows XP system disk. Solution: this is not a hardware fault. One reason is that the model uses a new SATA hard disk, which can be solved by disabling the SATA option in the BIOS. Take hp nc/nx63xx/nc64xx and related commercial laptops using SATA hard disks as an example: Start the la

When installing the Linux system, you may encounter such a confused problem: Hard Disk partitioning.How to plan the partition structure and how to divide a hard disk (including a mobile storage device) is more reasonable? To reduce the risks and unnecessary troubles caused by unreasonable hard disk partitioning, we will introduce how to plan the partition structure of a hard disk. I. Hard Disk category and physical GEOMETRIC STRUCTUREHard Disks are mainly SCSI, IDE, and popular

"Extensions" folder is not tube, is placed some of the necessary mouse keyboard driver files, etc., there are two files "org.chameleon.Boot.plist" and "smbios.plist", We open it with Notepad, found that there are some key value pairs of parameters, if interested to understand is to search for "chameleon start parameters", I believe there are a lot of information on the Internet.6. Restart the computer and start the installationBefore choosing to boot to boot, enter the BIOS to check whether to

The file names of each Hardware Device in Linux are in the Linux system, and each device is treated as a file. And almost all hardware device files are in the/dev directory. the relationship between the disk connection mode and t

host at the same time? Answer: Because boot loader has a menu function, you can choose a different kernel to start it. Because of the control transfer function, you can load the loader in other boot sector (the default layout of the loader in windows has the control transfer function, so you cannot use the loader in windows to load the loader in linux) Problem 2): If linuux is installed on a SATA hard disk, you can use INT13 of the BIOS to obtain th

other boot sector (the loader default layout of Windows has the control handoff function, so you can't load Linux loader with Windows loader)2): Assuming that the Linuux is installed on a SATA hard drive, the boot loader and Kenerl files can be booted from the BIOS INT13, and then the kernel will start to take over the system and detect the hardware and attempt to mount the root directory to obtain additional drivers. But the kernel does not know

Before you solve the problem, you should know the relevant knowledge: 1. What is AHCI functionality? Full name Advanced host Controller Interface: Advanced Host Controller Interface, an Intel-led technology that can perform the potential acceleration of SATA drives, which can increase disk read and write speeds by up to 30%. 2. What is SATA HDD? Refers to Serial ATA hard drives, which are evolved by Pat

32-bit CPU is detected, it "ruthlessly" rejects the installation and cannot be installed in virtual machine software such as VMware. It seems that Microsoft has not considered the 64-bit WinXP to be compatible with the 32-bit CPU, that is to say, the vast majority of computers are and WinXP 64 "missed." How is the installation different? The ISO image will be downloaded, restart the system with CD-ROM boot into the installation interface, WinXP Pro RC2 Installation interface and installation
