Item Type: Debugging Card Material: PCB Color: Yellow Instructions for Desktop Four-in-One Diagnostic Card: 2. The desktop four-in-one diagnostic card connects to the 1st pin of the motherboard's LPC interface, as shown in the figure. To correctly position the card, note that it has two starting points for the LPC interface, with the triangle indicating pin 1 (Figures 3 and 4). 3. Ensure the desktop four-in-one diagnostic card's interface and the motherboard's LPC interface are correctly aligned. If they are misaligned, it cannot be used. The card can be aligned with the 1st pin of the motherboard's LPC interface. If the motherboard's LPC interface has more or fewer pins, ignore them. 5. Display 00: Switch interfaces for testing. If there's no PCI slot or the PCI-E is not running the code, switch to PCI. Each motherboard has only one interface that can run the code. If it displays 00, the user should switch interfaces for testing. 6.
