Your computer is telli</span></td> </tr> <tr> <td colspan="2"><hr /></td> </tr> <tr> <td colspan="2"><span class="postbody">By: <br />One beep from your computer at startup can make your whole day. Just ask anyone that has turned on the <br /> PC and suffered the agony of several beeps and then nothing. <br /> When you purchase a computer, it will arrive with the BIOS (Basic Input/Output System), pre-installed on an <br /> EPROM (Erasable Programmable read Only Memory), chip on the main/motherboard. When you start your <br /> computer the CPU (Central Processing Unit), sends control of the PC to the EPROM BIOS. The BIOS is part of <br /> the POST (Power-On Self Test) of the computer. Once the BIOS receives the go ahead from the processor it starts <br /> its magical journey through all the components and peripheral devices attached to the computer. CMOS <br /> (complementary metal-oxide semiconductor), hold the data that is accessed by the BIOS setup. Basically, the <br /> CMOS is the reason that you can unplug your computer and retain the startup and BIOS information. CMOS is <br /> maintained on the motherboard in an always-on state supported by a battery installed on the main board. <br /> Much like the human mind, when we wake up in the [url=http://www.gotprintsigns.com/abercrombiepascher/‎]abercrombie pas cher[/url] morning our brain remembers that we have eyes, ears, a [url=http://www.jeremyparendt.com/jimmy-choo.php]jimmy choo chaussures[/url] nose <br /> and so on. We know the town we live in. You can go to work, stop by the post office, the grocery store and back <br /> home without having to spend time perusing a map for directions to each one. Your computer works much the same <br /> way. Without a memory device to instruct the computer on what?s where, the operating system and other software <br /> would literally have to take the time to locate each part of [url=http://www.mnfruit.com/louboutinpascher.php]louboutin[/url] the PC and its components every time they are loaded. <br /> Fortunately, the BIOS take care of that for the processor, operating system and components. [url=http://www.teatrodeoro.com/hollisterde.php]hollister[/url] <br /> How the BIOS works. Every computer comes pre-loaded with the BIOS on the motherboard. Motherboard <br /> manufacturers work long hours with BIOS manufacturers to make sure the information in the BIOS is specific to [url=http://www.sandvikfw.net/shopuk.php]hollister outlet sale[/url] the <br /> needs and components of the motherboard. Although there are a number of BIOS manufacturers, the two most <br /> popular are AMI (American Megatrends Incorp.) and VIA. BIOS simply put, is a program and not an actual <br /> device. It is the software that informs the computer at startup of all the devices (input and output) attached to the PC. <br /> The BIOS also lets you know when there is a problem. It accomplishes this by checking for known devices and <br /> makes [url=http://www.mnfruit.com/airjordan.php]jordan[/url] sure they are still attached. When the BIOS detect a problem it sends a series of beeps to the motherboard <br /> speaker. This series informs the user of what the problem is, at least as well as the BIOS can determine. Lets say <br /> your video card has gone the way of the XT model computer, the BIOS senses that it has died or is not installed. The <br /> BIOS sends a series of beeps to the onboard PC speaker to inform you of the problem. Pretty neat! The problem is <br /> that no manufacturer of BIOS uses the same beep series. This is why it is important for you to know the BIOS <br /> software manufacturer for your specific PC. We?ll explain how to find this out later. <br /> How do I know if the BIOS are working? That?s easy, if your computer starts and you get a single short beep, <br /> the BIOS is working and has found and relayed the information about the input/output devices to the CPU. If you <br /> turn on your computer and nothing happens at all, the problem is probably in your power supply (this assumes that <br /> you have it plugged in properly) the BIOS is probably still working but the computer can?t start because of a power <br /> problem. If all is well, the BIOS will find all the attached input/output devices, send a single short beep [url=http://www.jeremyparendt.com/Hollister-b5.php]hollister france[/url] to the internal <br /> speaker and the computer will [url=http://www.sandvikfw.net/shopuk.php]hollister sale[/url] start the boot process. <br /> OK, so who?s the boss?? BIOS, CMOS or POST? If we must choose, it would be the (Power-on, Self-test), <br /> POST. The POST is simply the process of the BIOS using the information from CMOS to start the computer. <br /> Remember, the BIOS information is stored in CMOS memory maintained by an onboard battery. <br /> Three ways to change and/or update the BIOS. Unlike ROM (read-only memory) the EPROM BIOS can be <br /> changed or updated. The term for changing the EPROM software is referred to as flashing. You may have over <br /> heard someone say that they need to flash the BIOS with a new update. Don?t worry if you have never heard this, <br /> well, maybe you should worry a little. Computer components change on a daily basis and the BIOS needs to be <br /> flexible enough to be able to change with them. All computers allow the user to change the BIOS software and how <br /> the computer reacts to input/output devices. The standard is to offer the user a way in to the software via a hotkey at <br /> startup. Normally this hotkey is the F2 key, the Del (Delete) key and in some cases the F1 key or a combination of <br /> keys. Start your computer and watch the bottom left corner on the screen. This should let you know which key to <br /> press to enter the BIOS setup. The BIOS setup, sometimes called the CMOS setup, allow the user to make <br /> changes on the fly and save them. Let?s say you added an external modem to your PC on Communication serial port <br /> number 1(Comm1), and no matter how many times you install the drivers, you can?t get the PC or Windows to <br /> recognize it. Chances are that the BIOS does not know that the modem exists. Entering the BIOS setup and <br /> changing it to allow the [url=http://www.moncleroutletosterblade.com]moncler[/url] use of Comm1 will fix the problem and let the PC know that a device exists on that port. This <br /> is the most common use of the BIOS setup and also the easiest to do. WARNING: it is just as easy to totally screw <br /> up your system by making changes in the BIOS setup. So be careful [url=http://www.moncleroutletosterblade.com]moncler outlet[/url] and make sure you know how and what to <br /> change. Changing the wrong settings can render your computer useless. There, we warned you twice, that?s because <br /> we want you to think twice before you change the BIOS. Second is the Flash BIOS update from the manufacturer <br /> of the BIOS. This is a software program that the manufacturer of the BIOS sends out periodically to insure the BIOS <br /> conform to new equipment and standards. You can normally get this software upgrade for the manufacturer and <br /> sometimes from the motherboard manufacturer. Be careful?be very careful installing the software and be positive <br /> [url=http://www.mnfruit.com/airjordan.php]jordan pas cher[/url] that it is for your specific BIOS. Always follow the manufacturers instructions exactly. The third way is replacing the <br /> BIOS chip. Replacing the chip may be your only recourse and should be left to professional computer repairmen. <br /> How do I know which BIOS I have? That also easy, the computer will actually tell you. If you?re fast enough, <br /> you will see the BIOS name and version on the screen the moment you turn it on. If you are not a speed-reader you <br /> can access the BIOS setup and retrieve the information from the setup program. You may also contact the <br /> motherboard manufacturer and find which BIOS was installed on that board. <br /> As stated earlier, the beeps mean something. They can [url=http://www.lcdmo.com/hollister.php]hollister pas cher[/url] give you information on problems that the BIOS <br /> encounters. Contact your BIOS manufacturer to find out what each beep series means. Armed with this information <br /> you may be able to figure out why your PC has stopped working and avoid scratching your head and noticing this <br /> huge question mark hovering over your PC. <a href="http://www.mpl1.com" target="_blank">www.mpl1.com</a> <br /> <br />相关的主题文章: <br /> <br /> <br /> [url=http://www.dzxgtzyj.gov.cn/E_GuestBook.asp]hollister[/url] <br /> <br /> [url=http://www.bigxm.net/home.php?mod=space&uid=675035][/url] <br /> <br /> [url=http://222.219.29.206/E_GuestBook.asp]hollister[/url]</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
