ELILO is an EFI-only boot loader.  It simply won't be able to run in a 
non-UEFI BIOS environment.

You can load your kernel and initrd directly from iPXE (ignoring ELILO 
completely).  For example:

   kernel product/common/ramdisk/rh64vmlinuz \
       initrd=rh64_02042014_initrd \
       imgurl=ftp:product/common/ramdisk/rh64rootimg_02262014.gz \
       panic=20 rdblacklist=nouveau nomodeset
   initrd product/common/ramdisk/rh64_02042014_initrd

If your kernel was built with CONFIG_EFI_STUB enabled, then this script 
will work without modifications for both UEFI and BIOS environments.
