Hi, I got a few centos 5 boxes installed for tests and find the following confusing messages from ?dmesg? command: ? Your BIOS doesn't leave a aperture memory hole Memory: 4043392k/5242880k available (2397k kernel code, 150460k reserved, 1222k data, 196k init) ? The machine has only 4GB memory chips installed only, so where comes the number ?5242880k? for memory?
