Re: x86_64 virtual memory map

[Bob Zhang]

who can answer my first email of questions ?thanks .

Good idea , yes ,yes ,BIOS probes the real physical RAM size ,and
linux kernel will get this by e820 BIOS call(INT 0x15) .we can check
e820 output to judge whether firmware 's problem or not.

 I will grab e820 output information from dmesg .now ,I can't access
that machine , so wait .thanks .
