memtest86+.. How do I load it with pxelinux?

May 29, 2007, 9:16 PM

Post #1 of 7 (3382 views)

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.

LABEL memtest86+
MENU LABEL Memtest86+
kernel pxeknife/memory_test/memtest86+/memtest86+-1.65

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.

Yep. Got the right one. I am running a pre version of pxelinux though.
Would the fact that I'm using "kernel memtest86" break it? Or should it
still just work?

Any hints on which ones? I'm using the first version that the CTRL-N
network info display thing was added. Would it be a buggy one?

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

Yes, that's a buggy one. Upgrade and you'll be fine.
