What is a ROM Memory ?
ROM is the read-only memory.It is different from RAM.It is the solid-state semiconductor memory only read the beforehand stored data . Its characteristics is that as soon as the data storaged it can not be changed or deleted. ROM of the stored data is stable, the stored data will not change in the power off.Its structure is relatively simple, the read-out is more convenient, and thus commonly used for storing various fixed program and data,such as the computer BIOS chip.Becasue ROM can not rewrite the information and can not be upgraded, it is now rarely used.
For ease of use and high-volume production, the further developments of ROM are Programmable ROM (PROM),Erasable Programmable Read Only Memory (EPROM),Electrically Erasable Programmable Read Only Memory (EEPROM),Flash ROM.etc..
Flash ROM is the useful .Flash ROM write fast,can write with low voltage. It has large capacity and low cost.It is used in Compact Flash/CF，Smart Media/SM，Security Digital/SD，Multimedia Card/MMC，Memory Stick/MS, and also used in PDA ,Pocket computer ,andriod smartphone.
Solutions of the Several Errors about "to Interrupt Normal Startup Press Enter"
Sometimes you will meet the problem when you boot your computer the screen displayed the error "to interrupt normal startup press enter" .For this problem ,there are several situation:
Case 1 :Computer booting display "to interrupt normal post,press enter!" and it would pass in 5 minutes.
Stop at "to interrupt normal post,press enter!",it means the operating system was not problem. Maybe the hard disk ,display card or memory loose.If you have checked them and the problem was still,most likely the hard disk has bad tracks or sector.The best you carry the computer to maintenance organizations.
Case 2 :Boot appears "to interrupt normal startup, press enter", but does not press Enter, keyboard does not respond to, and keyboard light is not bright.The computer can not boot at all. Read more

1.Hardware compatibility: the control frontmentioned in the latest hardware compatibility list, all hardware is included in the list
Dust caused by the motherboard does not recognize hard drive
A friend's computer is often unable to start, and occasionally into the system is also frequent crashes, preliminary judgment computer there is a problem caused by a virus or hard drive itself. Prepare in accordance with the first soft, hard, simplest to most complex maintenance principles to come up with the latest Kaspersky antivirus software on the hard drive killing, but using the boot disk into DOS mode, but the prompt can not find the drives, it appears that the virus is unable to carried out.
Restart the computer and into the motherboard BIOS, hard disk parameters inappropriate, but the automatic detection does not recognize the hard drive. Only seems to check the hardware, open the case, unplug the hard drive power cord and data cable is Read more
1.The noise of the chassis.
Fault phenomenon: to upgrade the CPU, the computer every time you turn noise particularly large. But after a while, the voice returned to normal.
Fault Analysis and Processing: First check whether the CPU fan fix bad chassis work and structure of some low-quality, easily in the boot of work caused by resonance, increased noise, in addition to the CPU fan and chassis fan motor add a little oil to try. If it is, it is best to replace the chassis because the chassis of the box single book.
2.The temperature rising too quickly.
Fault phenomenon: a computer running when the CPU temperature rose quickly, boot and only a few minutes the temperature rose from 88 ° F to 124 ° F and when 128 ° F to stabilize, no longer rising. Read more

the First Computer Virus and the Most Powerful Virus in History?
A computer virus is a computer program that can replicate itself and spread from one computer to another. The term "virus" is also commonly, but erroneously used, to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability.Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by other computers.

Create a USB Boot Disk for Windows 7
If you want to create a USB boot disk for Windows 7, make sure that you backup the files that you have saved on the USB flash drive that you will use. You would need to reformat the drive and all of the files on it will be lost. Also check the BIOS to find out whether your computer is capable of booting from a USB flash drive.Now we can use the tool Diskpart brought by Windows 7 self.You will found it's very easy to create such a USB boot disk.
1.The USB flash drive must have more than 4 GB of available space on it.Click the "Start" button on the taskbar and select the option "All Programs" from the menu list. Select "Accessories" and scroll down the list until you see "Command Prompt" and right-click on it. Click on "Run as Administrator". Read more
Computer Failure Caused by CPU Problems
Computer failure caused by CPU is although varied, but also summed up in nothing less than the frequent crashes, POST displays the operating frequency of repeated changes, and can not boot due to excessive overclocking, and system power-up without any reaction of several way.Of course,we should cope them in different ways.
This computer failure are quite common, mainly due to generally poor work by the cooling system,
What is the difference between BIOS and CMOS
In the daily operation and maintenance of computer process, often hear a number of statements about the BIOS settings and CMOS settings , many people often confuse the BIOS and CMOS. This article describes the CMOS settings and BIOS settings of distinction between the basic concepts and linkages.
What is BIOS?
The BIOS, is actually a computer's Basic Input-Output System, its content integrated in the computer a ROM chip on the motherboard, the main computer system holds the most important basic input and output procedures, system information set , turn the power on self test procedures and systems bootstrap procedures.
Function of the BIOS
BIOS ROM chip can not only see on the motherboard, and the BIOS management board to a large extent determines whether the performance is superior. BIOS management features include:
1. BIOS interrupt service routine
BIOS interrupt service routine is essentially a programmable interface between the hardware and software in the computer system, mainly used a interface between hardware and software . For example, DOS and Windows operating system on floppy disks, hard drives, optical drives, keyboards, monitors and other peripheral equipment management, are built directly into the system BIOS interrupt service routine basis, and the operator can also access the INT 5, INT 13 other breakpoints directly to call BIOS interrupt service routine.
2.BIOS system setup
Computer components configuration records are placed in the CMOS RAM chip, mainly preserved in the basic situation of the system, CPU features, soft and hard drives, monitors, keyboards and other parts of the information. In the BIOS ROM chip with "System Setup", mainly used to set the parameters of the CMOS RAM. This program in boot time by pressing a particular key enter setup mode, and provides a good interface for the operator to use. In fact, this set the CMOS process parameters also called "BIOS settings." Once the CMOS RAM chip on the computer configuration information is incorrect, the light will make the system to reduce the overall operating performance, soft and hard drives and other components can not be identified, which will lead to a serious system hardware and software failures.
3. POST Power On Self Test
Computer power on, the system first by POST (Power On Self Test) procedure to check each device on the internal. Usually complete POST will include the CPU, 640K base memory, 1M or more extended memory, ROM, motherboard, CMOS memory, serial and parallel, video card, keyboard, harddisk subsystems for testing, once the self-test problems are detected, the system will give a message or a warning whistle.
4. BIOS boot bootloader
After system completed POST, ROM BIOS on the first follow the system CMOS settings stored in the boot sequence search for soft and hard drives and CD-ROM, network servers effectively boot drive, read into the operating system boot record, then gives the system control to the boot record,and lets boot record to complete the system by a smooth start.
