Hi, Line 762 of efi/main.c (git firmware branch) should be changed to if (hdr->version < 0x20b) { Without this change syslinux efi64 gives out "handover protocol unimplemented error" and fails to boot. With this change syslinux boots the kernels fine (tested with 3.6.9 and 3.7rc6 kernels). Please fix this. Thanks in advance. Regards. Keshav
