[Your bios only has 32bit resources enabled. Try to reconfigure PCIe (mem BAR) address space (MMIO) settings in RBSU/BIOS (something like "MMIO above 4G" or "Above 4G Decoding", or "MMIO base" set to lower value)] Is there any setting or way to fix this or a specific revision of the bios that allows this setting?
[After reading through some other posts I found Ctrl + A mentioned to bring up a hidden menu that has that option in it. the other posts mention ML or SL line but it also works on the DL as well.
