- No. The dumpfile must be on the system disk. The system locates
- the dump file and "opens" it, very early in the boot process; long before
- other disks would be mounted.

- The dumpfile need not be full size. If you have a smaller dumpfile
- and set up your SYSGEN parameters properly, VMS will write a partial dump.
- What VMS thinks are the most significant portions of memory will be dumped
- first. DUMPSTYLE must be set to 1 to do this.
-
- It is also possible to write a dump to your primary paging file
- (which must reside on the system disk). You must copy such a dump to
- another file to release the pages in the paging file that are occupied by
- the dump. The copy may be made on another disk if you wish. In order to
- do this, SAVEDUMP must be set to 1.
-
- I may have missed a parameter or two so carefull study of the
- manuals would be a good idea. (My biggest system has a whole 32Mb of
- memory so I've never been reduced to these expedients).
