SMP Memory Diagnostic for Linux
I have downloaded the BradyTech SMP Memory
stand-alone bootable memory diagnostic. Download at http://members.shaw.ca/yehudi2/memtest86-3.5.tar "C" Source Code plus Makefile is included, + binary "memtest.bin" which is stand-alone bootable memory diagnostic, that can be installed onto a boot floppy as follows dd if=memtest.bin of=/dev/fd0 or "memtest.bin" can be configured in /etc/lilo.conf as a Lilo section for a stand-alone bootable image. Seeing as I do not have an SMP machine available I would like to know if the SMP code works. Could someone with a "Core X" machine, "X" > "1" please try it and post whether the diagnostic correctly detects the number of CPUs present, and proceeds to test correctly? |
Hi,
I really don't think anyone will take you up on this. Basically security will be the issue. Trust! No one will openly trust at this level for a test request of this type. I for one would not but paranoia is good. Especially with things happening on the Internet & social engineering. Maybe the use of a school, University or College system would be possible as a test bed. :hattip: |
Yes, that is a problem. The source is there, but I'd have to look through it before I trust booting this.

Hi,
I agree 'H'. Really don't want to spend time searching through code today. :hattip: |
SMP Memory Diagnostic - Trust (אמונה)
If you don't trust the "SMP" go to "config.h" and
comment out the line referring to "#define SMP" then rebuild the diagnostic as follows: cd ./memtest86-3.5 make clean make install Check the date/time stamp on the following file memtest.bin to ensure that you have just "built" it under Linux. You can make a bootable floppy disk as follows dd if=memtest.bin of=/dev/fd0 You can make a bootable partition for LiLo by doing cp -v memtest.bin /boot/memtest.bin Then configure an additional Linux partition with /sbin/liloconfig Finally manually edit this new partition in the file /etc/lilo.conf to have parameters img = /boot/memtest.bin label = memtest root = /dev/"whatever" - Whatever is root partition read-only and install the new "LiLo" by typing /sbin/lilo Please note that I included the "memtest.bin" ready-to-boot image as a convenience, in case people did not have Linux. Usually people with older operating systems can read "tar" archives, so I did not "bzip2" this archive before I uploaded it to the reflector as http://members.shaw.ca/yehudi2/memtest86-3.5.tar People without Linux (i.e. "DOS" users) should still be able to extract "memtest.bin" even though they are unable to build it from the "C" sources. |
