Because pxelinux.0, bootia32.efi and bootx64.efi are different names, so 
I can put them in the same path, no problem for this, i.e.
$ ls -alFh /tftpboot/nbi_img/{*.0,*.efi}
-rw-r--r-- 1 root root 157K Apr 22 15:30 /tftpboot/nbi_img/bootia32.efi
-rw-r--r-- 1 root root 160K Apr 22 15:30 /tftpboot/nbi_img/bootx64.efi
-rw-r--r-- 1 root root 105K Apr 22 15:30 /tftpboot/nbi_img/gpxelinux.0
-rw-r--r-- 1 root root  74K Apr 22 15:30 /tftpboot/nbi_img/lpxelinux.0
-rw-r--r-- 1 root root  42K Apr 22 15:30 /tftpboot/nbi_img/pxelinux.0

My goal is to put all the required COMBOOT files in the same path 
(/tftpboot/nbi_img/), too. No subdir, so that I can make the goal of 
"One DHCP/PXE config for BIOS, EFI32, and EFI64 clients":

Actually not x86 (32-bit), I use x86-64 kernel from Ubuntu or Debian, 
and of course, it could boot both on EFI64 or BIOS arches. So I should 
change the goal as:
"One DHCP/PXE config for BIOS (legacy PXE boot) and EFI64 (uEFI network 
boot) clients"

Thanks!
