[elschman]

as result kernel can not be found cos of wrong path...

:option_pbs
set opts "vga=791 video=vesafb:ywrap,mtrr ramdisk_size=15384000 rw initrd=initrd"
set kernel http://192.168.0.254/isos/pxeboot-proxmox-backup-server_4.0-1/linux26 ${opts}
initrd http://192.168.0.254/isos/pxeboot-proxmox-backup-server_4.0-1/initrd
imgstat
chain ${kernel}

.....
