Thank you for your rapid reply, I have found a live CD that does somewhat what I want, but the tools is not up to date, but check it out Hiren Rescue CD, I will also check out your recommendations.
Now then, I have downloaded syslinux bootloader to put on the CD, is it possible to burn the iso files to the disc like this, samsung.iso/Westerndigital.iso/ibm.iso and boot off them from syslinux?
A collaboration would be quite awesome, since I am still quite new to configuring bootloaders and make them work.
Oh, I just thought of something, since all diagnostics tools (that I have tried) use dos, perhaps the way to go is with FreeDOS and launch the diagnostics from there. There might be one problem though (or maybe not, I am not all that in to the different versions of DOS), one of the diagnostics tools use Caldera DOS (spelling?).
