This requires that you have a DHCP and tftp server configured and setup properly on your network, and is probably not for the faint of heart.You can also check the Lenovo Support website's driver matrix. Make sure the firmware bootdisk is in linux 'dd' format, as the self-extracting disks from the IBM website cannot be booted directly as such.
