To: linux-kernel
We have a dual Opteron 244 on a Tyan Thunder K8W/S2885 m/b.
It is a custom compiled vanilla 2.6.5 kernel.
It has 3 x 2GB RAM modules installed, 2 on one CPU and the other RAM
module on the other CPU. The BIOS reports 6144MB on boot up.
An AGP line reports (see dmesg below)
agpgart: Maximum main memory to use for agp memory: 5944M
during bootup, so the kernel looks like it thinks we have ~6GB available.
But a free reports 5GB, not 6GB.
Does anyone know where the missing 1GB is?
cheers
Stuart
