Hi

Continuing trying to run EPICS ioc in RTEMS-MVME2304, I am facing the
following error message.

***** Initializing NFS *****
"(null)" is not a valid command pathname.
"" is not a valid command pathname.

I am using a tftp/nfs server to provide the boot file and argument
file. However there is another BOOTP/DHCP server is running on the
network which is to boot LINUX for installation. What I f eel is that
the reason of error is the conflict between the two bootings (the
bootp server and tftp/nfs server) perhaps and the CPU is trying to
boot from the DHCP/BOOTP server after loading the boot file from
TFTP/NFS server. However I am not sure if my feeling is correct.

Below is the complete output after isuing the nbo command from
PPC1-BUG to initiate network booting in the MVME2304.

Please provide me your kind advice and guidance to proceed.

With Best Regards

Zia
