herboard. The Chipset will consist of a micro circuit group contained in several integrated chips or one or two integrated Very Large Scale Integration (VLSI) chips. VLSI is a chip that has more than 20.000 circuits. Th
e Chipset will determine the following things:
- Amount of RAM that can be used by the motherboard
- RAM Chip Type
- Cache size and speed
- Processor type and speed
- Expansion slot type that the motherboard can accommodate.
rd. The ROM Chip contains instructions that can be accessed directly by the microprocessor. Unlike RAM, ROM chips take back what they contained in spite of the computer being turned off. R
OM contents cannot be deleted or changed in normal way. Data Transfer from ROMS is slower than RAM, but faster than any disk. Some examples
of ROM chips can be found in the motherboard including the BIOS ROM, electrically erasable programmable read-only memory (EEPROM), and Flash ROM.
ally the BIOS location in the motherboard is marked. This BIOS system is a very important part of the computer. If the CPU is said to be a computer brain, the system BIOS is the heart of the syste
m. The BIOS will determine what hard drive the user has installed, where there is or not the 3.5 inch floppy drive, what kind of memory is installed and many other important parts of the system hardware at startup time. Th
e BIOS is responsible for serving the relationship between computer operating software and various hardware components that support it. Some of the following responsibilities include:
- Hosting Program setup for hardware
- Test the system in a process called POST
- Control all aspects of the boot process
- Extracting audio and video error codes when there is a problem during POST
- Provides basic instructions for computers to manage devices in the system
- Find and execute any BIOS code in the expansion card
- Find the boot volume or sector of any drive to start the operating system
- Ensure compatibility between hardware and system.
S ROM. Having this program in a permanently saved ROM means providing data when power is turned on. Therefore, the PC will be able to use it to boot up the system.
se the ROM chip has instructions that can make the device work properly, it should sometimes be reprogrammed or replaced when the instruction for the upgraded device is needed. Unlike EPROM, EEPROM chips can be removed using a normal power voltage higher than using an ultra violet beam. When the B
IOS system is loaded in EEPROM, it can be upgraded by running certain instructions.
gy. Toshiba creates terms for the ability of the chip can be removed in seconds or very quickly. Flash ROM Set the BIOS on most new systems. This Flash ROM can be reprogrammed under the use of special software co
ntrols. Upgrade the BIOS by using a special software known as flashing. BIOS is implemented in flash memory known as plug-and-play BIOS, and it supports plug-and-play tools. The Chip retr
ieves data when the computer is turned off so that information is permanently stored. Flash memory is cheaper and more powerful than the EEPROM chip technology
D. Expansion slots
mputer. The device includes a video card, an I/O card, and a sound card. Here is an example of expansion Slot image.
Audio/Riser Modem (AMR) is a plug-in card for Intel motherboards. AMR contains audio and or modem circuits. Intel Specification 46-pin connector edge to provide digital interface between card and motherboard.
AMR has all the analog functions, or code, required for audio and or modem operation. AMR evolved into a kartuC
ommunications and Networking Riser (CNR), which adds functionality to LAN and home networking.
