I did an upgrade from 5.1 to 6.5 SP3 (using the overlay CD) on a Compaq
Proliant DL-380 G2 server. After all files were copied to the server, the
server restarted with storage adapters loaded and SYS volume mounted.
Right after network board driver (N100) was loaded the server returned an
error message saying “TCPIP.NLM modules failed to load”. It asked me if I
wanted to exit the intall and I chose NO and it just sat there doing
nothing. I rebooted and tried again, same problem.

Any suggestion to fix the problem? Thanks.
