The published miniumum requirements of a DBAN competitor says that the processor of the system with the HDD to be erased must be at least an Intel 486. That product creates a boot disk from which the DOS program is run. My assumption is that DBAN requires the subect system to be already booted into DOS before running DBAN from diskette. Is there a minumum processor or DOS version requirement for running DBAN? I need to wipe the HDDs of both old IBM PS/2 286 and 386-based systems.
