Troubleshooting Flash ROM Updates Updating Software
E - 4
Some BOOTP and TFTP implementations require a specific directory for the MSS.SYS file. In this
case, the path should not be specified in the bootptab file—the file must be placed in the bootptab
directory. If BOOTP cannot be used to configure the MSS’s IP parameters, configure them by hand
using the following commands:

NOTE: Before the MSS can be booted across an IP router, the router must be configured to
perform proxy arping for the MSS.
E.2.3 MOP
Copy the MSS.SYS file to the MOM$LOAD directory. The MSS.SYS filename is the only parameter
that the MSS needs to reload via MOP. Make sure the service characteristic is enabled on the host’s
Ethernet circuit, then reload the server using the following command:

E.3 Troubleshooting Flash ROM Updates
Many of the problems that occur when updating Flash ROM can be solved by checking the
following:
NetWare The loadfile must be in the login directory; the MSS cannot actually log
into the fileserver.
TFTP The file and directory must be world-readable.
The loadhost name and address must be specified correctly, and their
cases must match those of the files on the host system.
FTP must be enabled on the host; several major Unix vendors ship their
systems with TFTP disabled.
MOP The Ethernet circuit service characteristic must be enabled.
The MOM$LOAD search path must include the directory containing the
MSS.SYS file.
