Syslinux - May 2007 - memtest86+.. How do I load it with pxelinux?

I've just spent at least half an hour swapping files, downloading things 
and stuffing around with memtest86 and memtest86+. I can't get either to 
start from pxelinux.

Currently I have "memtest86" as the filename, and i'm trying to
load it
direct (not trying to use memdisk or anything). This just results in a 
near instant reboot.
Am I doing something wrong? I can't find much info at all about how to 
load these tools. I'd just use their ISO, but I haven't got a working CD
drive anywhere.

is what I'm using.

Make sure you got the correct version of memtest86; the correct version
has a .bin extension (which you have to change unless you use 3.50-pre
with LINUX instead of KERNEL in your config file.)

Some of the 3.50-pre releases had a bug when it came to booting
memtest86; that has been fixed.

As easy as pie:

1. Download the Memtest86 source code from http://www.memtest.org/#downcode

2. cd (source dir); cp precomp.bin /tftpboot/memtest86

3. Configure PXE booting by a file containing:
default memtest
label memtest
kernel memtest86

I documented this in
https://wiki.fysik.dtu.dk/niflheim/System_administration#network-booting-memtest86
