e820 map: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009f000 (usable) BIOS-e820: 000000000009f000 - 00000000000a0000 (reserved) BIOS-e820: 00000000000ce000 - 00000000000d0000 (reserved) BIOS-e820: 00000000000dc000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000000f6f0000 (usable) BIOS-e820: 000000000f6f0000 - 000000000f700000 (reserved) BIOS-e820: 000000000f700000 - 000000003f6f0000 (usable) BIOS-e820: 000000003f6f0000 - 000000003f6f8000 (ACPI data) BIOS-e820: 000000003f6f8000 - 000000003f6fa000 (ACPI NVS) BIOS-e820: 000000003f700000 - 0000000040000000 (reserved) BIOS-e820: 00000000ff800000 - 0000000100000000 (reserved) 118MB HIGHMEM available. 896MB LOWMEM available. Is the hole between 0x36f6fa000 and 0x3f700000? And what would be the proper way of fixing it (assuming that IBM won't issue a fixed BIOS)?
