Here is a better description of my problem.
                                                                     
                                                                     
                           
I am building a new RHEL AS 3 system from Linux version 2.4.21-4.EL (Red
Hat Linux 3.2.3-20)
                                                                     
                                                                     
                           
I put all the networking configuration information in, and I can connect
to the new initial ram disk system.  I supply the DASD device numbers
of "151,200,201,202,203"
                                                                     
                                                                     
                           
I then LOGN to ROOT on the initial system and see some of the following on
the system console
