Hi there,
I'm currently using CentOS 4.3 (Server edition) in a HP DC 5100 with the
IntelR 915GV chipset, powered by a PIV 3.0GHZ.
Now I'm facing a problem, with memory.
I got myself 4GB of memory, the system bios detects it correctly, but in
Linux can only see around 3.5gb memory. With the default kernel-smp (I use
hyperthread) or with kernel-hugemem , I have the same results.
Is there any way to workaround this issue?
It is probably the 4Gb memory hole issue - various 'things' reserve
memory below 4GB so hiding the real memory from the OS.
Your BIOS may have a mapping option to map some of this hidden real
memory to above 4Gb - however, you need to use a hugemem kernel to
access this memory.
