Study Notes

CPU Sockets

  • Intel sockets include LGA 775 (T), LGA 1366 (B), LGA 1156 (H1), 1155 (H2), 1150 (H3), and 1151 (H4)
  • AMD sockets include AM2/AM2+, AM3/AM3+, AM4, FM, and FM2

Features of Modern CPUs

  • Entry Level/Mainstream/High End: Categories like i3, i5, and i7/i9 vary in features generation to generation. Features include core count and availability of turbo boost and hyper-threading.
  • Hardware Virtualization: Modern processors have hardware virtualization capabilities (e.g., Intel's VT-x) to reserve resources at the hardware level for individual virtual machines.
  • Multiple Cores: Modern CPUs have multiple processor cores, allowing them to function like multiple processors. Core counts can be 2, 4, 6, or more.
  • Cache Memory (L3 cache): Higher-end processors usually have more L3 cache than lower-end processors. For example, an i3 processor might have 2-4 MB, while an i7 of the same generation might have 6-8 MB.
  • Hyper-Threading: Allows the processor to appear to the operating system (OS) as having twice as many cores as it actually does. Each core can run two processing threads simultaneously.
  • Turbo Boost: A feature in many modern processors that allows the CPU to run at speeds above its standard speed when under demanding load and below power and thermal thresholds. Typically, only one or some cores will run faster, not all.

POST (Power-On Self-Test)

  • Checks for the presence and functionality of hardware devices.
  • Often accompanied by HDD spin-up sounds, keyboard light blinks, and chipset checks.
  • Halts the system if a serious fault or error is found.
  • Errors are usually reported as beep codes or error messages.
  • A POST card can help diagnose more serious faults.

Booting a Computer

  • Except for data in CMOS, the computer has no record of attached devices or addressing.
  • Each boot/reboot requires re-learning device information.

BIOS Startup Screen

  • Displays vital system information, such as:
    • Motherboard manufacturer and model
    • BIOS manufacturer, version, and date
    • Serial number
    • Prompt to enter setup program
    • Processor make and model (and sometimes speed)
    • Memory type and amount

Cold Boot (Hard Reset)

  • Occurs when a system is fully powered off and then on, requiring the complete boot process.
  • Interrupts all computer functions, potentially causing problems during saving/writing.
  • Happens when power is interrupted and the OS isn't properly shut down.

Warm Boot (Soft Reboot)

  • Occurs when a system is already running and is reset using menu options or commands within the operating system.
  • Can also be triggered by the Alt-Ctrl-Del key combination.
  • The POST process is not run in its entirety.

Steps in the Boot Process

  • 1. Power supply starts, generating necessary voltages.
  • 2. CPU initializes and resets; one core randomly starts.
  • 3. CPU starts the system ROM BIOS bootstrap loader.
  • 4. BIOS programs load into main memory ("shadowing").
  • 5. BIOS checks hardware configuration; beep codes for failures.
  • 6. Video ROM initializes; displays information on the monitor.
  • 7. Other device ROMs (e.g., network adapter, hard drive) start.
  • 8. BIOS performs test routines (e.g., memory count). Error codes displayed if necessary.
  • 9. Expansion busses and plug-and-play devices are checked and assigned resources; checked against the ESCD (Extended System Configuration Data) in CMOS.
  • 10. Device information displays; indicates new hardware.
  • 11. Boot device selected based on CMOS settings (e.g., hard drive, USB). Boot record sought, OS loaded.
