1.2 bios and cmos

  1. 1. A+ Hardware<br />Section 1.2 BIOS and CMOS<br />Made By : Gagandeep Singh<br />
  2. 2. What you learn today<br />CompTIA A+ 220-701 , Section 1.2,<br />Explain motherboard components, types and features.<br />BIOS/CMOS/Firmware.<br /> - POST<br /> - CMOS battery.<br />
  3. 3. What you learn today<br />Basic Input Output System (BIOS) overview.<br />Complementary metal-oxide semiconductor (CMOS).<br />Accessing the CMOS settings from the BIOS software.<br />
  4. 4. Starting the computer<br />Everything has to talk to computer<br /> - Keyboard language translation.<br /> - Monitor language translation.<br /> - Hard drive language translation.<br /> - CD-ROM drive language translation.<br />If only there was some basic system for communicating between diverse components.<br />
  5. 5. The CMOS<br />Complementary Metal Oxide Semiconductor (CMOS).<br /> - The type of memory.<br />Backed up with a battery.<br /> - What’s the date and time settings.<br />Stores the BIOS and configuration details.<br />Doesn’t need to be very big<br /> - 128 bytes of content.<br /> - Integrated into the Southbridge. <br />
  6. 6. BIOS<br />Basic Input Output System (BIOS).<br /> - The Firmware (software)<br />It is software that tell which monitor and components are attached to computer.<br />Every PC has a BIOS ROM.<br />
  7. 7. The CMOS battery<br />Maintains the BIOS configurations.<br />A bad battery will require a BIOS configuration on every boot.<br />Can often reset the BIOS configuration by removing the battery.<br />
  8. 8. Configuring the BIOS <br />
  9. 9. The secret button <br />Launching the system setup<br /> - Delete<br /> - F2<br /> - Ctrl-s<br /> - Ctrl-Alt-S<br />
  10. 10. POST<br />
  11. 11. POST (Power on Self Test)<br />Test major system components before booting the operating system.<br /> - Main System <br /> - Video<br /> - Memory<br />Failures are usually noted with beeps or codes.<br />
