• SPI Flash (BIOS): The schematic shows the pinout for the BIOS chip. If the board powers on but has no display, checking the VCC and CS (Chip Select) pins on this chip is vital. Corrupted BIOS data is a common failure on H61 boards.
• PCI-E Slots: The schematic includes the pin definitions for the x16 and x1 slots. Technicians use "Diagnostic Cards" inserted into these slots; the schematic helps interpret the error codes displayed by the card.
• Crystal Oscillator: The 32.768kHz Real-Time Clock (RTC) crystal near the PCH is a common failure point. If this crystal or its associated capacitors are damaged, the board will not retain BIOS settings or may fail to boot.
