D.3 Troubleshooting Flash ROM Updates

Many of the problems that occur when updating Flash ROM can be solved by checking the following:

NetWare	The loadÞle must be in the login directory;
	the MSS cannot actually log into the
	Þleserver.
TFTP	The Þle and directory must be world-read-
	able.
	The loadhost name and address must be
	speciÞed correctly, and their cases must
	match those of the Þles 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.
