Hi, I have two questions The test case specified in http://lists.osdl.org/pipermail/hotplug_sig/2006-June/000614.html shows how to add 1GB of memory to the kernel that has been booted with just 2 GB memory. 1. Is it possible to specify the *STARTING ADDRESS* of the memory to be added in addition to the *SIZE*. This emulates memory hot add in hardware when I physically plug-in memory DIMM into a particular DIMM slot. 2. Is the same feature available to emulate hot remove of memory DIMMS? Thanks Bithika
