\t Its possible to have multiple roots and choose between them.
\t-c Set machine type. [e.g 3000]
+\t-D Enter debugger
\t-h This help message.
+\t-I Inhibit sync negotiation. Option value is bit-encoded targets.
\t-k Reserve the first 4M of fast mem [Some one else
\t is going to have to answer what that it is used for].
\t-m Tweak amount of available memory, for finding minimum amount
\t segment. The higher priority segment is usually faster
\t (i.e. 32 bit memory), but some people have smaller amounts
\t of 32 bit memory.
+\t-S Include kernel symbol table.
\t-t This is a *test* option. It prints out the memory
