I have good news. memtest86+4.2 can boot on pxelinux 5.10-pre2 using 
elf.c32.
The problem is solved!!

type in pxelinux.0
 >elf.c32 memtest
only this line. but, "memtest" is not "memtest.bin"

quote README.build-process in memtest86+ source directory

We must build "memtest" from source code.
how to build memtest86+4.2 with gcc-4.7 :
https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1071209

you told me  memtest "image"  has the problem. I could find the way.
thank you for your big advices.

I want the way is True.
