+.Nd memory files
+.Sh DESCRIPTION
+The special file
+.Pa /dev/mem
+is an interface to the physical memory of the computer.
+Byte offsets in this file are interpreted as physical memory addresses.
+Reading and writing this file is equivalent to reading and writing
+memory itself.
+Only offsets within the bounds of
+.Pa /dev/mem
+are allowed.
+.Pp
+Kernel virtual memory is accessed through the interface
+.Pa /dev/kmem
+in the same manner as
+.Pa /dev/mem .
+Only kernel virtual addresses that are currently mapped to memory are allowed.
+.Pp
+On landisk, physical memory is contiguous.
+The kernel virtual memory begins at address
+.Li 0xc0000000 .
+.Pp
+Writeability of these devices is controlled by the system
