BIOS (Basic Input / Output System) is the program used by microprocessor to get PC started once it has been turned on. It resides on EPROM (Erasable Programmable Read Only Memory). Once the system starts, BIOS controls all the operations of the system. It checks for the attachments or peripherals or devices like RAM, Keyboard, CPU etc., It takes care that all the peripherals work together.
Once initializing and checking is completed, the operating system is loaded into the RAM from the hard drive or diskette drives. BIOS settings can be changed depending on the users requirements during the system start up by pressing a specific key. It has a UI, which lets the user make changes as per the user’s needs.
Using the user interface, a user can set the system clock, configure the hardware, enable or disable components, selecting the primary, secondary boot devices, password setting etc., It also has a small library which describes each option for the better understanding of the user.
RAID 0 and RAID 1 Structure
Basic BIOS can create RAID 0 and RAID 1 structure, whereas sophisticated BIOS provides the feature of creating RAID 5 array and the ability to manage the RAID server.
Nonvolatile BIOS memory is used to store BIOS settings. It is also known as CMOS RAM because of its low power consumption feature. It resides on motherboard. BBI (BIOS Boot Specification) API can be used to change the way the system boots. MS-DOS depends on BIOS for input / output tasks within the computer.
BIOS are rewritable. They are stored on rewritable memories. The process of rewriting their contents is known as Flashing. BIOS software is upgradable. BIOS, guides the computer to perform some basic functions like, booting etc. It also identifies and configures hardware. BIOS is a part of motherboard, hence it doesn’t matter which operating system is being used i.e., Windows XP or Windows Vista or Windows 7 and so on.
SD Card devices
SD cards are employed in many devices including car navigation system, tablets, video game consoles, personal digital assistants (PDAs), cellular phones, eBooks, PDAs, smartphones, etc. Their usability in many devices to provide high storage in small cards has made them popular.
How to access BIOS set up utility?
Keys to access BIOS set up utility for some of the BIOS manufacturers are given below:
Recover Data after Disk Boot Failure
Due to disk boot failure, we lose all our files stored on the hard drive. To fix the issue, we need to repair Operating System. If we are unable to repair, try reinstalling OS which leads to formatting the hard drive. To recover formatted data back you can make use of Remo Recover, which helps you to retrieve all the files without any loss.
Recover Data from Unbootable HDD
If the computer doesn't start in a normal way due to disk boot failure, it might display an error message like "Please Insert a CD to Boot". In such scenario, we cannot access our data stored on the hard drive. The article explains how you can recover files under such condition.
