how bios work in motherboards?
455242
BIOS is an Acronym for basic input/output system, the built-in software that determines what a computer can do without accessing programs from a disk. On PCs, the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions.\n\nThe BIOS is typically placed in a ROM chip that comes with the computer (it is often called a ROM BIOS). This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, though, many computer manufacturers design systems so that the BIOS is copied from ROM to RAM each time the computer is booted. This is known as shadowing.\n\nMany modern PCs have a flash BIOS, which means that the BIOS has been recorded on a flash memory chip, which can be updated if necessary.\n\nThe PC BIOS is fairly standardized, so all PCs are similar at this level (although there are different BIOS versions). Additional DOS functions are usually added through software modules. This means you can upgrade to a newer version of DOS without changing the BIOS.\n\nPC BIOSes that can handle Plug-and-Play (PnP) devices are known as PnP BIOSes, or PnP-aware BIOSes. These BIOSes are always implemented with flash memory rather than ROM.

if you mean thebios startup, the problem is proobably in the way youplaced the ram.\nmake sure the RAM's are put in nicely, the tap is locked, and that if you use more than one RAM slot the RAMS are the same (same speed, company)\n\nIf your RAM cards are with a different memory, this is how they should be (persuming you have 4 slots, and your MB is not very old)\n\nAB ----  DC\nY    -    X\n\n\n\nSo, lets say A,B,D,C, are cards inserted. AB and DC do not have to be equal; A can be 64 and B 1024\nBUT Y(A and B) has to equal X(D and C)\n\nHere is a more clear ex\n\n\nA -     b          -   d   -  c\n1024 -  512    -     1024  -  512\n\n\nif d and c are not used,this doesnt count \n\n\nthats how my ASUS P5ND2 SLI deleuxe works

Hi this is chirag.\n\nYou can access the bios from desktop. For that you need a software which can be used in windows mode. You can write bios from Windows through this software..\n\nYou can find such utility in the given web site.\n\nhttp://mainboard-drivers-and-utilities.free-driver-download.com/Aopen/13008/Aopen-Mainboard-WinBIOS-Utility-For-Windows-2000-XP.html

No he means Mother Board, Thats a piece of Hardware in a computer, It is what all your memory, cd roms, hard drive, and more connect, See a Mother Board it the big flat board in your computer sometimes Green or brown or more colors, anyway theres a system BIOS thats software that Links everything to the mother board and makes it run properly, wich reminds me i need to update mine

You might be better off going to Crucial.com or one of the other good memory sites and letting them test your machine.  They can tell you exactly which configuration will and won't work on your motherboard.  It's possible to save a lot of money by getting an expert's advice on that.

usually not, it has to be done in the bios window at power on\n\nthere may be some way of doing it, but it needs to be a special application from your motherboard manufacturer if it is, i'm not aware of any such things

Yes, just go to your computer manufacturer's website and they'll have the latest bios for you to download for free.

If this is a computer at work, don't mess with your BIOS.  You could get fired.

When a computer is first turned on, or rebooted, its bios performs a power-on self test (post) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the post will display an error message; however, if the bios detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the bios has detected.

F8 opens the safe mode. I think that on a Compaq it is F2 or F5 but Im not sure. Also you want to open the BIOS not the CMOS (compilmentry metal oxide semiconductor) they are all connected but that is the battery on the board that keeps a trickle charge going to the ROM CHIP which is what holds the BIOS settings. Basicly the CMOS is also what will clear and reset the BIOS there is usually jumper on the board next to it which you just switch from 1,2 jumper to 2,3 jumper it then shorts the 2 posts and resets. Also you can also just take the battery out for about 10 min and put it back in and then it resets the bios. This comes in handy if your computer wont boot sometimes from a corrupt program or driver. If you have the manual for the computer it should tell you what to press to get into the BIOS.

each motherboard manufacturer has it way to upgrade the Bois ,some use the bois it self to do the operation ( by enter the Bios setting and from it u can browse the new bios image which is BIN file ,or some manufacterer us a windows based program to do the operation\nAnd you need to upgrade the bois for different reason ( fix a bug is the old version ,support new CPUs ,increase the motherboard stability and reliability

BE CAREFUL!!\nChanging your PC's BIOS can completely kill your computer!\nSome types of virus will try to do this!!!\n\nBasic Input Output System\nBIOS\n\nEvery time you start or re-start your computer, one of the first things your computer's Mother Board (MoBo) does is to read the BIOS.\n\nThis tells it what kind of devices are supposed to be there.\n(Hard drives, CD-ROM, et cetera)\n\nThe BIOS tells your computer how much memory is supposed to be there.\n\nThe BIOS tells your System whether to boot from the hard drive first, or to look for a floppy drive or CD drive to boot from first.\n\nLike when you first wake up, you become "Self Aware".\nYou know, without even having to think, that you are a human, you have eyes, ears, a nose, arms, legs, whatever, and you know that you are (usually) in you bed in your house.\n\nIf any of that changes, like if you are spending the night at a friend's house, your "BIOS" would tell you that your normal operating environment has changed.\n\nThe BIOS doesn't "Load" like you operating system.\n\nAfter the BIOS is read and your system goes through a few checks to make sure everything is working, then your Operating System (O/S) loads (Windows, Unix, DOS, what ever).

It usually depends on the manufacturer of the motherboard.  If the machine is bought from a brand name such as Dell, HP, Compaq, etc... you'll probably have to go to their respective website and look up something like support or downloads.\n\nHowever, if it is a homebuilt machine then you'll need to open the machine a determine the manufacturer of the motherboard as well as the model number.  After that then you go to the manufacturer's website and try to find BIOS updates that you can download.\n\nLast thought on BIOS updates though, be very certain that you are downloading and installing the correct BIOS, otherwise you can render your PC inoperable.

If you mean the bios password then yes this way is a method that may work altho rather a dodgy method, i would suggest flashing the bios using the jumper settings - should have a scematic diagram in your motherboard manual. if the password is on windows or a program on the os then this will not correct it you will either have to brute force hack it/use a program or do a system refresh and loose any data that you needed to access within the passworded section.

you will have to set it in BIOS

What is the "purpose" you mean?\n\nYou can search the net and read all kinds of technical jargon describing it to you.  But, I would think of it this way...\n\nThe BIOS is one layer between the hardware and your operating system (Windows for example).  Communication between both hardware and software is made possible as a result.  The BIOS doesn't care about the commands themselves necessarily.  Its main responsibility is to provide an open channel of communication and some hardware settings like the speed of traffic that flows to memory or the CPU.
