Complete the following steps until the problem is resolved:

1. Update the UEFI firmware to the latest version.

2. Check the event log and resolve any issues related to the device.

3. Validate that the device is supported for the server (see Lenovo ServerProven website). Make sure that the firmware level on the device is at the latest supported level and update the firmware if applicable.

4. Make sure that the adapter is installed in a correct slot.

5. Make sure that the proper device drivers are installed for the device.

6. Resolve any resource conflicts if running legacy mode (UEFI). Check legacy ROM boot orders and modify the UEFI setting for MM config base.

   Note

   Ensure that you modify the ROM boot order associated with the PCIe adapter to the first execution order.

7. Check Lenovo Support Portal for any tech tips (also known as retain tips or service bulletins) that might be related to the adapter.

8. Ensure any adapter external connections are correct and that the connectors are not physically damaged.

9. Make sure that the PCIe adapter is installed with the supported operating system.

3. Save the settings and restart the system.

4. If the error recurs with the highest device resource setting (1GB), shutdown the system and remove some PCIe devices; then, power on the system.

5. If the reboot failed, repeat step 1 to step 4.

6. If the error recurs, press Enter to access System Setup Utility.

7. Select System Settings > Devices and I/O Ports > PCI 64–Bit Resource Allocation, then; modify the setting from Auto to Enable.

8. If the Boot Device does not support MMIO above 4GB for Legacy Boot, use UEFI Boot Mode or remove/disable some PCIe devices.

9. DC cycle the system and ensure the system is enter UEFI boot menu or the operating system; then, capture the FFDC log.
