Wrong-o.  Read the original posting again.  The user was talking about TSRs,
programs that reside in memory.  This is totally different than an area set
aside for a RAM drive, which could be recovered.  With TSRs, interrupt vectors
tend to be replaced and are lost when the system restarts and the COMMAND.COM
is reloaded.
