Previously, we looked at Setting up a PXE environment for OS installations. This post will build on that by adding the MemTest86+ to the PXE environment, so you can easily run memory checks on network-connected machines.
This will be a really easy one. First, download the MemTest86+ binary
/tftpboot directory and decompress it:
cd /tftpboot fetch http://www.memtest.org/download/4.20/memtest86+-4.20.bin.gz gzip -d memtest86+-4.20.bin.gz
/tftpboot/pxelinux.cfg/default file to add this menu entry
LABEL memtest86plus MENU LABEL MemTest86+ 4.20 linux memtest86+-4.20.bin
That's it, you should now be able to run MemTest over the network.
PXELINUX File Extensions
One extra thing to point out in case you're interested...
The PXELINUX menu entry above says
linux memtest86+-4.20.bin instead of
kernel memtest86+-4.20.bin because when you use the
PXELINUX looks at the file extension '.bin' and treats the file like a CD
boot sector (which it is not in this case). When I tried
kernel I just
got a stream of:
8200 8200 8200
on the screen over and over. Alternatively, you could rename the MemTest
file to something without the
.bin extension, such as
kernel memtest86p420 and it would work.
The SYSLINUX wiki mentions this on the Common Problems page.
