When multiple PCI Express* adapters are installed, the following error can display during POST, and the server halts:

0146 - PCI out of resource

To resolve the issue, follow these steps:

1. Temporarily remove the add-on PCI Express* adapters.
2. Update BIOS/firmware to the latest revision.
3. Disable unused devices and/or their OpROMs in BIOS, like onboard SATA/SAS controllers and onboard NICs.
4. Make the following changes in the BIOS:
   • Go to BIOS Setup => Advanced => PCI Configuration.
   • Set Maximize Memory below 4 GB to Disabled.
   • Set Memory Mapped I/O above 4 GB to Enabled.
   • For Memory Mapped I/O Size, select the required MMIO size for the add-on PCIe* adapters.
5. Install the add-on PCI Express* adapters one at a time and see if the server boots properly.
