I’ve been looked for a CPUZ type program for my Linux (Ubuntu) so I could see the bios info and what motherboard specs I have in my computer. This little scrips works great.
First launch terminal
Applications > Accessories > Terminal
sudo lshw -html > Myhardware.html
The terminal will ask for your password, enter it and then it will generate a HTML file in your home folder called Myhardware.html. Launch your home folder and double click on Myhardware.html to get all of your specs.
