Hi,all:
This is my memory status from "dmesg":
Memory: 4673020k/5242880k available (1334k kernel code, 44532k reserved,
672k data, 156k init, 3800960k highmem)
But I found that available memory size is much less than physical memory
size.My server is Dell6650 with P4 Xeon*4 and 5G Ram.
My kernel version is 2.6.12-rc1-mm1.Could any one tell my the reason?Thanks.

The other dell6650 with 16G ram under kernel 2.6.11-rc4-mm1 is more oddness.
Memory: 16116752k/16777216k available (1855k kernel code, 135136k reserved,
702k data, 164k init, 15335296k highmem)

The first 800 and sum odd MB of memory are not considered high memory,
so it will not appear in the output. By taking a quick look at your
numbers, it seems fine

There is another dell2650 with 2G memory using option "CONFIG_HIGHMEM4G":
Memory: 2075744k/2097024k available (1858k kernel code, 20408k reserved,
704k data, 160k init, 1179520k highmem)
2097024-1858-20408-704-160=2073894.It looks be close to 2075744. So I
consider it would be fine.
But when I use option "CONFIG_HIGHMEM64G" in these dell6650
Memory: 16116752k/16777216k available (1855k kernel code, 135136k reserved,
702k data, 164k init, 15335296k highmem)
16777216-1855-135136-702-164=16639359.
16639359 is far from 16116752.I think "The first 800 and sum odd MB of
memory" would be in the area (1855k kernel code, 135136k reserved, 702k
data, 164k init, 15335296k highmem).Is this right?
