Hi Shao, The cmdline patch would be very helpful. How do I build gpxe with it?

The above is a sample for how you can pre-populate a few IP parameters, then use gPXE's 'config' command to hack them just before trying to boot to a PXELINUX that will boot from some webserver. I'll be you could adapt this to your needs. Alternatively, there is a patch for gPXE that allows you to pass commands to gPXE from another boot-loader, such as Syslinux. You might find this convenient, so you could have something like: LABEL site_a KERNEL gpxe.lkrn APPEND set ip=192.168.0.3; set gateway 192.168.0.1 LABEL site_b KERNEL gpxe.lkrn APPEND set ip=192.168.1.3; set gateway 192.168.1.1 where you'd then only need a single gpxe.lkrn who could have the following embedded script: #!gpxe set netmask 255.255.255.0 set dns 10.113.114.8 config set 209:string pxelinux.cfg/default set 210:string http://webserver/ chain ${210:string}pxelinux.0 The patch is called something like the "gPXE lkrn initrd cmdline patch." - Shao Miller _______________________________________________ gPXE mailing list [email protected] http://etherboot.org/mailman/listinfo/gpxe
