passing static ip address to initramfs

Hi All,

Does anyone know if passing static ip details to the initramfs via a syslinux/pxelinux menu entry works?

The line in question reads (line split for easier reading):

append initrd=http://x.x.x.x/otw/cz/live/initrd1.img

console=ttyS1,57600n8 boot=live union=aufs noprompt

ocs_live_run="ocs-live-general" ocs_live_extra_param="" ocs_live_keymap=""

ocs_live_batch="no" ocs_lang="" nolocales


vga=normal fetch=http://x.x.x.x/otw/cz/live/filesystem.squashfs

The official way defined in the manpage is:


I have found various pages explaining how to deal with the AUTOCONF field, putting none, off, <blank> all to no effect. Also I am guessing that if you are providing static ip and loading squash_fs via a fetch: line you would leave the SERVER_IP field blank (I have also tried it with the target ip). Every combination I have tried ends up with initramfs issuing bootp requests regardless:

IP-Config: eth0 hardware address 00:1e:c9:f7:56:27 mtu 1500 DHCP RARP
[   20.146038] tg3: eth0: Link is up at 100 Mbps, full duplex.
[   20.146038] tg3: eth0: Flow control is off for TX and off for RX.

I do not have the ability to implement a dhcpd setup since the machines are based on live public connections at the datacentre.

Could anyone help with the correct syntax or any reports of being able to boot via static?

Many thanks,
