Finally, the "-f" parameter indicates the name of the file (under /tftpboot on laci@lcls-dev1) containing the sequence of values to be loaded into memory.
It is set to /rtems/4.10.2/powerpc-rtems/beatnik/img/netboot.flashimg.bin for both production and development. Note that the mount for tftp is mapped to from the environment variable $TFTPBOOT on the development and production control systems. Therefore if you "cd $TFTPBOOT" the path following "-f" should exist.

- At this point, you've confirmed the flash memory contains the right data. The netBoot software will recognize several commands from your keyboard, and it's listed them after you've interrupted its boot process.
- Normally when it runs, netBoot attempts to download the software that you ultimately want to use. To do so, it keeps several parameters in non-volatile memory (NVRAM.)
- Now you're going to set those various parameters and record them in NVRAM. Press "c" to change the parameters that netBoot will use to download software. Keep in mind that your own processors IP address must be entered under "My IP", just as it's name.
- Typically, only the fields marked "My IP", "My name" and "Command Line Parameters" will have values unique to your processor. All other fields should be entered as you see here. If you have questions, please ask a Controls Software Engineer from theEPICS Team.
- The field "Command Line Parameters"is set to:
- (booting from NFS): INIT=/boot/epics/iocCommon/user , followed by a path to your boot-up script. If you're using the AFS filesystem, which is common at SLAC, then your path will typically be something like /u/ <two-chars> / <login user-id> /path-to-example . If you are booting out of the shared lcls group space, the boot-up script is /boot/g/lcls/epics/iocCommon/"<your-node-name>"/startup.cmd . See the example below. Please note that the same DNS and the NTP servers for development and test-facility are used.
