May be these URLs help. The SE supports IPL from CDROM or FTP.
For IPLing into an LPAR, there is the option to directly load from the MP3000 or HMC CDROM device. It also allows you to IPL via FTP from a server holding the SuSE Linux S/390 files. Find this button near the ‘LOAD’ button (if you have upgraded to the latest MCL, see Chapter 5 page 17). For using the HMC to run this operation, there is no button ‘Load from CDROM or server’ available on the HMC’s console. Start a remote session to the SE via the single operation button. The SE’s remote console then shows the ‘Load from CDROM or server’ button. 15
