[ipxe-devel] Booting diskless Ubuntu from iSCSI

I am trying to boot Ubuntu 15.10 from an iSCSI target with iPXE, but it
fails to load the grub menu.

Here is the message I get:
Grub says:
Starting Hardware Identifier
Registered SAN device 0x80
Booting from SAN device 0x80
error: attempt to read or write outside of disk 'hd0'
Entering rescue mode...
grub rescue>

I managed to iPXE boot the Ubuntu 15.10 installer and successfully
installed Ubuntu to the iSCSI target, but it will not boot properly.
I am using FreeNAS as the iSCSI target.

Attached are my ipxe.menu and Ubuntu preseed.cfg files
I am using the ubuntuiscsiinstall menu item to install Ubuntu and
the identifyhardware menu item to boot it.

Any help would be appreciated.
