[syslinux] pxelinux 5.x, 6.x memtest problem

[Németh Péter]

Hi guys!
I tried to boot memtest86+ v4.2 (renamed memtest.bin to memtest), and i have issues to boot it with pxelinux 5.x and greater.Pxelinux 4.06 works fine both memtest 4.1 and 4.2.
With version 6.00 no error message caught, only writes out dots. Any keypress does a reboot.With version 5.01 the error message is the follow:Loading images/memtest/memtest86... okBooting kernel failed: Bad file number
The pxelinux.cfg/default file contents:DEFAULT memtest2
LABEL memtest    KERNEL images/memtest/memtest.original    APPEND console=ttyS0,9600n8
LABEL memtest2    KERNEL images/memtest/memtest86    APPEND console=ttyS0,9600n8
PROMPT 1TIMEOUT 100
Any ide how to solve this?
Thx, Peter
