Hi, I read a few articles on linux virtual memory management such as this one : http://lwn.net/Articles/75174/ which say that earlier linux kernel could only use memory slightly below 1 GB. They have given the reason for it but I am unable to understand.They further describe the use of High memory and low memory. Could anybody please explain the reason for kernel not being able to use the 1 GB completely? Also please provide references for high memory and low memory. Thanks Vaibhav Jain
