Not being familiar with Windows dumps, but only with Linux kdump (which is 
basically
a mini-Linux distro running in 64MB - that includes the initrd.img and + RAM 
space)
which can dump the entire memory on to whatever you want (NFS, disk, USB, etc). 

How does Windows natively/normally do its dump? Is it just dumping the entire 
memory space
on the local disk? Or do you have to set special flags to do so from the driver?
