This would create such a segment, ranging from 256MB to 1792MB: DEFSEG SWAPPING 10000-10000 EW 10001-6FFFF EN BTW, the first EW part is needed to store the Linux swap signature, which should be saved permanently. The remaining EN part does not need to be saved for a swap device, and it will load a lot faster than a regular DCSS. Another note: Adding "dcssblk.segments=NAME" to your kernel parameter line only makes sense if you have dcssblk compiled into the kernel. If not (e.g. SLES10) you'd need to load the module with "modprobe dcssblk segments=NAME" instead.
