Thanks to lshw, I avoided buying too much RAM for my motherboard. I wanted to know for sure what type of RAM I was running, and luckily it also listed my motherboard RAM capacity: 2GB. It lists loads of other stuff too: detailed information on system devices, (PCI, USB) BIOS, and even disk partitions! This is more about my machine than I ever knew. I really wish I could find a manual for my eMachine’s motherboard. I’m not sure if it even came with one. I’m saving up to replace this with a self-built machine, but it’s going slowly.
