Hello Everyone,

I see same error that memtest4.2 can't boot on pxelinux 5.0 and later.
However, linux kernel 3.8 and DOS FD DISK image are ok on one.
also memtest4.2 can boot on isolinux 5.0 which is build from same source
code.

I just pushed the debug log which have boot message of pxelinux 5.1.0
pre2 with memtest4.2.
of course, i did how to get the log that Mr.Fleming said.

Please see this link for debugging syslinux.
