...Fall BIOS – Instructor: Mrs. Nicholas – NT1110 – 1 May 2014 Lavon Hawkins BIOS SUMMARY Lavon Hawkins BIOS SUMMARY BIOS BIOS: The BIOS is software which is stored on the motherboard. It tells the computer how to perform a number of basic functions such as booting and keyboard control. It is also used to identify and configure the hardware in a computer such as hard drive, floppy drive, optical drive, CPU, memory and so on. CMOS: The complementary metal oxide semiconductor is the type of semiconductor chip on the motherboard which stores the system information and computer settings such as date, time, hard drive settings, boot sequence, parallel part settings, on-base audio and video etc. Firmware: Firmware is a combination of software and hardware. Computer chips that have data or programs recorded on them are firmware. POST: The POST or power on self-test is a test the computer does when it first boots up. It’s to verify all the hardware is working. If all checks out it usually gives a single beep. If not a beep code could come up. Beep Code: A beep code is an audible code which is generated during the POST (Power On Self Test) when the BIOS has an issue but has not made it all the way up the boot sequence that it can give you the error as a message on the monitor BIOS update: Updating the BIOS can fix or enhance aspects of a computers performance. Or it may provide support for newly installed hardware. 1 Flash BIOS update: A BIOS chip...

...ends with the entire operating system being loaded is known as the boot loader (or bootstrap loader). The term creatively came from early designiners imagining that before a computer “runs” it must have it’s “boots strapped”. The boot loader’s only job is to load other software for the operating system to start. Often, multiple-stage boot loaders are used, in which several small programs of increasing complexity sequentially summon one after the other, until the last of them loads the operating system. Boot Devices The boot device is the device from which the operating system is loaded. A modern PC BIOS (Basic Input/Output System) supports booting from various devices. These include the local hard disk drive, optical drive, floppy drive, a network interface card, and a USB device. Typically, the BIOS will allow the user to configure a boot order. If the boot order is set to: 1. CD Drive 2. Hard Disk Drive 3....

...BASIC INPUT OUTPUT SYSTEM [BIOS] Seminar Presented by Milind Chile - 2591 Dipti Borkar - 2778 Freddy Gandhi - 2787 Raghav Shreyas Murthi - 2804 Introduction The BIOS, short for BASIC INPUT OUTPUT SYSTEM is a set of built-in software routines that give a PC its personality. Although, less than 32 kilobytes of code, the BIOS controls many of the most important functions of the PC: how it interprets keystrokes (Ctrl + Alt + Delete), how it puts characters on the screen, and how and at what speed it communicates through its ports. The BIOS also determines the compatibility of the computer and its flexibility in use. Although all BIOSs have the same function; all are not the same. The BIOS governs the inner complexities arising out of the odd mixing of hardware and software. It acts as a link between the material hardware of the PC and its circuits, and the transcendent realm of software ideas and instructions. More than a link, the BIOS is both hardware and software. Like software, the BIOS is a set of instructions to the computer’s microprocessor. Like hardware, however, these instructions are not evanescent; rather they are coded into the hard, worldly silicon of PROM, EPROM chips. Due to the twilight state of programs like the BIOS, existing in the netherworld between hardware and software, such PROM-based programs are often termed firmware. The personality comes from the firmware code. This code determines how the computer will carry out the basic functions needed to make...

...AMIBIOS is a kind of BIOS manufactured by American Megatrends (AMI). Many popular motherboard manufacturers have integrated AMI's AMIBOS into their systems. The error of six beeps means that there has been an 8042 Gate A20 test error. This beep code is usually caused by an expansion card that has failed or the motherboard that is no longer working. Step 1. Six Beeps- 8042 Gate A20 test error is usually caused by an expansion card failure or that the motherboard that is no longer working. Step 2. Determine if it is the expansion card failure or that the motherboard is no longer working. Step 3. Power on the computer or restart. Listen to beeps very carefully. Step 4. Update the BIOS, replace Expansion Card, and replace the motherboard, if necessary. Step 5. Power on computer after installation of updated BIOS, or the Expansion Card, or the replaced motherboard. Step 6. Ensure to document all processes with outcomes before during and after installation of each program. Phoenix BIOS is manufactured by Phoenix Technologies.The beep codes from a Phoenix-based BIOS may be exactly the same as the true Phoenix beep codes and they may vary. A 1-3-1-3 beep code pattern means that the 8742 keyboard controller test has failed. This usually means that there is a problem with the currently connected keyboard but it could also indicate a motherboard issue. Step 1. 1-3-1-3 beep pattern, it means that ther is a problem with the keyboard or motherboard issue. Step 2. 8742 keyboard controller...

Disinfection & Removal Automatic Disinfection Allow F-Secure Anti-Virus to disinfect the relevant files. For more general information on disinfection, please see Removal Instructions. Technical Details The CIH virus was first located in Taiwan in early June 1998. After that, it has been confirmed to be in the wild worldwide. It has been among the ten most common viruses for several months. CIH has been spreading very quickly as it has been distributed through pirated software. History It seems that at least four underground pirate software groups got infected with the CIH virus during summer 1998. They inadvertently spread the virus globally in new pirated softwares they released through their own channels. These releases include some new games which will spread world-wide very quickly. There's also a persistent rumor about a 'PWA-cracked copy' of Windows 98 which would be infected by the CIH virus but F-Secure has been unable to confirm this. Later on, CIH was distributed by accident from several commercial sources, such as: • Origin Systems website where a download related to the popular Wing Commander game was infected • At least three European PC gaming magazines shipped magazines where the cover CD-ROM was infected - one of them even included a note inside advising users to disinfect their...

...and Logic Understanding The BIOS and POST Student Name Introduction Inside every PC is a BIOS, which stands for Basic Input Output System. In a nutshell, BIOS is software that interacts between a computer’s hardware and the operating system and software applications. There are several types of BIOS', ranging from the motherboard ROM BIOS to adapter BIOS' such as video BIOS, drive controller BIOS, network adapter BIOS, SCSI adapter BIOS, etc... These BIOS' are the lowest level of software in a computer providing a set of small programs or software routines that allow the hardware of a computer to interact with the operating system by a set standard. The Boot Process To get to the operating system, a computer must first boot from the BIOS. The BIOS performs a number of tasks when a computer is started. From initializing the microprocessor to initializing and testing hardware to starting the operating system. Starting a computer is not a simple task. It's a methodical process that is performed every time power is applied to a computer. This process will vary with different computers and different BIOS', but the overall goal is the same. When you first turn on a computer the very first operation performed by the CPU is to read the address space at FFFF:0000h. This address space is only 16 bytes, which is not nearly enough space to house the BIOS found on a motherboard. Instead, this location contains a special instruction...

...Short answers 4/29/2014 Erich Dippel 1. What are the major components of a motherboard? There are various roles that a motherboard plays. It acts as glue which binds all the components together. It main job is to coordinate with the various operations performed by the various components. It serves as a interface for all the modular singular components of a system like Central processing Unit or CPU, Random Access Memory or RAM, Storage device or hard disk. The main parts include a power connector, and i/o, a CMOS battery, primary/secondary IDE, processor, ports, memory controller hub, PCI and the BIOS. 2. Upgrading the motherboard will give you some performance improvements to your computer but why is this improvement limited? This improvement is limited because you have to upgrade more than just the motherboard to improve speed and other things. Upgrading the RAM and other things along with your motherboard is a good way to get all around system performance improvements. 3. What is the need for all the different busses found on a motherboard and why can’t these be replaced with a single bus? The difference between computer busses break down as so. Data width, Cycle rate, Device management and type. The data width and cycle rate are used to determine the bandwidth, or the total amount of data the bus can transmit. The device management indicates the maximum number of supported devices and the difficulty of configuring them. The memory bus is the interface between...

...Introduction The BIOS performs a power-on self-test when the system is turned on. This test is used to ensure that the system is functioning properly and to gather information about what the system contains. When a problem is identified with the system during the POST, the BIOS will normally produce an error message. However, in some cases the problem is detected so early in the test that the BIOS cannot access the video card to print the message. In this case the BIOS will produce a beeping pattern on the speaker to tell you what the problem is. The exact meaning of the beep codes depends on the type and version of BIOS that you have. The most popular types of BIOS are those made by Award American Megatrends (AMI) and Phoenix. AMI 6 Beeps: Keyboard controller / gate A20 failure The keyboard controller is a chip on the motherboard that communicates with your keyboard. It also controls the A20 gate that provides access to the high memory area (HMA). This component is indicating a failure. This is a problem with either the keyboard or the motherboard. Phoenix 1-3-4-1 Test 512 base address lines. Sometimes a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it. Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer and then placing them back into the slots, reset the memory and restart the computer.
