A NBI image is basically composed from a kernel, an initrd and some additional code. Since you want to make a PXE boot you can use 2 approaches: 1) use pxelinux (the LTSP default) but in this case you cannot do without an initrd, since pxelinux cannot boot a NBI image (just as Etherboot does), it needs to get a normal kernel and initrd just as another boot loader does (lilo, grub, etc). 2) use an Etherboot .zpxe image as 'filename' in the dhcpd.conf gile , the booting station will load etherboot via PXE (instead of pxelinux ->pxelinux.0) and from there Etherboot can load the NBI. This setup is not that easy to do, see: http://wiki.ltsp.org/twiki/bin/view/Ltsp/DHCP#Automatically_using_the_correct for the method of serving different 'filename' s, because first you have to serve an etherbpoot.zpxe image, and when the etherboot make a net boot of it's own you have to serve it the NBI image. May I ask why you don't want an initrd ? (LTSP always needs an initrd to boot from) hth, mitu -- mitu ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
