After my previous post about checking computer specs in Linux somebody asked an interesting question: how do you check your computer’s specifications if you don’t actually have any operating system to check them with?
In my opinion the easiest way to do this would be to download a disk image of a live CD for a lightweight Linux distribution, such as my favourite: ArchLinux. Once you’ve burned it to a disc you can put it in your computer and boot directly from the disc. ArchLinux is light and fast and will allow you to log in as root with command line access, where you will be able to run the commands I talked about in my other post to find your computer specs even for a computer with no OS or in other cases, for example where you don’t have permission to check with the current OS. If you’re not familiar with Linux don’t worry, follow the on-screen instructions and just type the commands I described. When you’re done checking you can turn off the computer and take out the CD and things will be just as they were before.
