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
The BIOS plays a
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.
What is ata first?
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
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
After Windows 7 is installed, When you enable the AHCI function of the SATA hard disk in the BIOS, the system will fail to start. The system will recover to normal only after you change to the IDE (ATA) mode. If Windows is installed in IDE mode, you need to reinstall the system to change the hard disk to AHCI mode in BIOS. This allows many users to reload data.I. Introduction to AHCI

nowadays, disk interfaces are mainly divided into two types: IDE (integrated drive electronics) and SCSI (small computer system interface ). They each have some differentiation or evolution, so the technical terms on disk interfaces are more and more complicated. Of course, the disk interface also has other technologies, such as optical fiber technology and familiar USB. The following describes the IDE technology. IDE is developed as a simple and cheap interface for PC. It places the hardware co
I. Category of disks
Disks can be divided into ATA (IDE), SATA, SCSI, SAS, and FC disks by interface type. According to the disk chip composition, it is divided into SSD and HDD. Because the mechanical hard disk is still the mainstream configuration, we call SAS, FC and SATA both refer to the mechanical hard disk.
The following is a brief introduction to Baidu Encyclopedia:
ATA,The full name is AdvancedTech
does not change, there are two solutions: If you only use Win98, it is relatively simple. In CMOS, set the second hard disk to none, however, the second hard disk is not recognized in pure dos. The second method is to re-partition the second hard disk, delete the primary DOS partition, and only split the extended partition. In this way, the drive letter will not be staggered. Of course, if the first hard disk has only one partition, there will be no problem of drive character staggered. Another

, mainly used for personal computers. PATA (Parallel Advanced Technology Attachment), the first implementation of the IDE Technology, came into being in the late 1980s s. ATA-2, with better PIO (Programmed I/O), supporting DMA mode, LBA addressing. ATA-3, increased reliability, with better power management features. The transmission speed reaches 133 MB/s until the ATA

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
Regarding the wireless internet is not smooth, the wireless network connection is not good question, this article has summed up many for everybody, and has provided the concrete breakdown description, the solution and so on. Hope that through this article, can make everyone convenient, simple to solve their own computer wireless fault.

serious problems. For example, if the WEP configuration is incorrect, the wireless client will not be able to obtain an IP address from the DHCP server on the wireless network (even if the wireless access point has no DHCP capabilities). If the wireless client uses a static IP address, it will not be able to ping the IP address of the wireless access point, which is often mistaken for the network is not connected.
The basic technique for determining whether a WEP configuration error or a netwo
1. Mixed wireless networks often fall off the line
Failure phenomenon
Use the Linksys WPC54G network card and Linksys WRT54G AP to build a wireless LAN that uses IEEE 802.11G protocols and a few 802.11B network adapters. The line is often dropped when using wrt54g for 54mb/s connections.
Fault analysis
In theory, the IEEE 802.11g protocol is backward-compatible with the 802.11B protocol, and devices usi
can cover, and the manufacturer has the default SSID settings for the devices it produces. For example, the SSID of a Linksys device is usually "Linksys." Admittedly, knowing the SSID itself does not allow your neighbors to break into your wireless network, but knowing the SSID can easily lead to other unintended consequences.
More importantly, if someone discovers the default SSID, it's easy to be the ta
your network will be assigned a unique key to transform the encrypted data. Since WPA uses dynamic key cryptography, the key is constantly changing, making it almost impossible to invade your wireless network. If your device supports encryption technology that is considered one of the highest levels of security for your wireless network, we will recommend WPA to you.
Why is WPA security important? If WPA is not configured in your wireless network, you are open to having someone intercept your
