C. Clock and Reset Generation
- Crystal Oscillator: Locate the 32.768kHz crystal (usually labeled Y1 or Y2). The boardview allows you to probe the nets connected to the EC and PCH to ensure the real-time clock is functioning.
- PCH (Platform Controller Hub): The boardview reveals the location of the BIOS chip (SPI Flash). Tracing the
SPI_CS#,SPI_MISO, andSPI_MOSInets is essential when reprogramming the BIOS, a common fix for "no post" issues on this revision.
Improved Functionality: Updates might also be made to enhance the functionality of the device or to add new features. This would involve changes to the boardview to reflect these improvements. dv15 mlk mb 112801 boardview updated
