Why BIOS beep what the concept behind it,could u please make me understood.
and i also want to know that is there any memory in the BIOS?
Is there any another reason which makes BIOS to beep?
If i repeatedly start PC without attaching any HDD and RAM will it has any effect on BIOS, does it makes my motherboad dead?
😒
<a href="https://en.wikipedia.org/wiki/BIOS" target="_blank" rel="nofollow noopener noreferrer">Bios</a> stands for basic input/output system.It is a boot program stored on a ROM(use EPROM lately, advanced type of ROM). This bios stored on the EPROM is often called as the BIOS chip. If it is required to be updated, it has to be flashed(formatted) using an appropriate software and then the new program written on the EPROM chip.
when u power on your computer, a POST(power on self test.) is performed. As the name suggests, it does self testing of various components to check whether all the components are working properly or not. If it is working properly, it will give a single beep and continue with the booting process. Remember that there are different companies making BIOS chips and some of their beep codes differ. So its wise to check the bios type(can be checked in bios screen by pressing delete key after starting the pc or on the 1st boot screen itself). AMI, IBM, Award,Phoenix are popular BIOS chip making firms.
The link given explains POST and the beep codes nicely. Check it <a href="https://www.computerhope.com/beep.htm" target="_blank" rel="nofollow noopener noreferrer">Computer POST and Beep Codes</a>
In short a BIOS may cause to beep once to indicate that it has completed POST successfully and is continuing into normal boot process or else it might boot different codes of long and short beeps to indicate an error. You can recognise the error by matching the beep with the code in the link given above. In most cases, the problem arises with the RAM only. Removing the rams, cleaning the golden contact points with a pencil eraser and puttung them back will solve the problem.(never touch with naked hands. static charge may kill ur ram. hold the rams by the edges).
in case the bios gets corrupt, it can be reset to default by removing the battery on the motherboard for a min or so and putting it back. or better still the <a href="https://en.wikipedia.org/wiki/Jumper_%28computing%29" target="_blank" rel="nofollow noopener noreferrer">Jumper %28Computing%29</a> can be cleared by putting in the right configuration(depends on the BIOS).
BIOS is a helping mechanism which assists us by doing the POST and letting us know if everything is fine to continue starting the computer. Thus helps us in diagnosing problems and rectifying them.
The BIOS screen(press delete key after starting computer) gives access to a lot more information to the user. Allowing the user to modify the setting suiting to his/her needs(eg. overclocking).
The BIOS is a chip and thus can become dead due to various reason. If dead, the motherboard wont proceed with booting unless it POSTs. So the BIOS chip can be removed and replaced with a new one and flashing it appropriately with updated firmware.
Remember, the BIOS is like the watchman of a building. He checks the entrants(components here) for issues and will let them pass if secure. If there exists an issue then he wont let them pass and will raise an alarm (will beep in this case). The appropriate step can then be taken.
