I'm not sure if I get this right, on Linux it shows BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e8000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 00000000defafe00 (usable) BIOS-e820: 00000000defafe00 - 00000000defb1ea0 (ACPI NVS) BIOS-e820: 00000000defb1ea0 - 00000000e0000000 (reserved) BIOS-e820: 00000000f4000000 - 00000000f8000000 (reserved) BIOS-e820: 00000000fec00000 - 00000000fed40000 (reserved) BIOS-e820: 00000000fed45000 - 0000000100000000 (reserved) BIOS-e820: 0000000100000000 - 000000021c000000 (usable) In addition, to boot Linux, we need to add pci=nommconf which says it disables MMCONFIG for PCI configuration.
