1648601: log server add to PC104 DHCP Configuration 

After discovering that some of the rtems IOCs were actually sending syslog messages, we investigated how we could get them to send them to our central syslog server.   While this can be hard-coded in the network header file, it seemed like a better approach to provide it through DHCP.  This option has been added to the DHCP server for all PC104s.  The default behavior for RTEMS seems to be to look for this in DHCP or set it to the boot host (which we don't want).  This means no configuration changes should be necessary to get the RTEMS IOC to pay attention to this parameter.  Whether it is initialized and used is a matter for the IOC developers.

Example boot output after this setting was made showing the Log server parameter:
