All, Two weeks ago I made this query and I got lot of suggestions and hints. I would like to thanks everybody who wrote. Please keep the spirit of helping other people with Linux kernel up. I was able to preserve memory across reboot, by allocating memory early in the boot sequence and making a small change in the allocating routine. It took me long to reply because I was in middle of relocating. If somebody needs detail explanation of exactly what I did, I can explain. Usman ===== Usman S.
