Minimum Hardware Requirements for Linux

Article by Tolga BALCI (23,398 pts ) , published Jun 3, 2009

Linux can run on very modest hardware, in fact as low as the archaic Intel 486 processors. Although the minimum requirements are different for the tasks you want to perform, you do not need to spend lots of money for a computer that will run Linux.

Linux Hardware Requirements

As our Managing Editor put it in his article, you do not need to spend an exorbitant amount of money to upgrade your CPU and RAM. You can do almost everything that you can do with your underwhelming Windows system on the same hardware with better performance. You just need to select the right distribution that fits your existing hardware and be brave enough to install and play with it; you really do not need anything else.

In terms of minimum hardware requirements, you can run Linux on a processor as slow as Intel 486. Considering that almost all of these processors are either recycled, dumped or donated to the museums, it is unlikely that you have one. If your current computer has at least a Pentium III processor or higher, you can run many distributions with the graphical desktop. If your computer’s hardware is lower, I am afraid you will have to go with the text interface.

Instead of talking vaguely with slow/fast/old/new adjectives, let’s base our ideas on the numbers. Here are distributions that have extremely low minimum requirements for a text-based interface (but multiuser and networked):

  • Slackware: Any 586 Processor, 32 Megabytes of RAM, 1 GB of Hard Disk Space, 4x CD-ROM (or floppy drive if you can’t boot from CD)
  • Gentoo: Any 486 Processor or higher, 64 Megabytes of RAM, 2 Gigabytes of Hard Disk Space, 4x CD-ROM

(Above hard disk requirements exclude swap space. Add 2 x Your RAM as the swap space; for example if you have 216 Megabytes of RAM, consider a swap space of 2 x 256 = 512 Megabytes. If the requirement is 1 Gigabyte, then you need to have 1 + 0.5 = 1.5 Gigabytes of hard disk space.)

OK, I admit that these are the minimum requirements for an up and running Linux system in text-only mode. Let’s see what do we need for a graphical desktop environment:

  • Puppy Linux: Any Pentium III processor, 256 Megabytes of RAM, 1 GB of Hard Disk Space, 4x CD-ROM
  • Fluxbuntu/Xubuntu: Pentium III processor, 256 Megabytes of RAM, 1.5 GB of Hard Disk Space, 4x CD-ROM

As you can see, the minimum system requirements are closely tied to the distribution you choose. Modern distributions such as Ubuntu, openSUSE, Fedora with their full graphic desktops which come with the default installation, require better hardware. However, I can safely say that any single-core processor over 1 Gigahertz and 1 Gigabyte of RAM (slightly higher than the latest smartphones) will run any Linux distribution at a reasonable speed, but of course, the higher the better.

I suggest you compare your current hardware with the system requirements listed in the Linux Distribution’s website. Most probably your current hardware will be much faster.

Re: I have an old 486 generation CPU
This one is really though but here is my shot.

For the hardware you have at hand, it is almost impossible to go for a graphical-screen implementation. What I would do with your configuration is as follows:

1. Either install Gentoo or Slackware in text only mode. Gentoo will take hours to compile but it will work very efficiently because all the software will be compiled according to your computer's hardware specifications. Once finished, I would go for a very lightweight window manager installation, probably IceWM. But set your expectations realistically and don't expect a smooth desktop experience.

2. You will be dedicating a lot of resources to the graphical screen and it is a question whether an MPEG2 Decoder + DVD will give you a smooth movie experience considering the CPU + RAM combination. I see it very unlikely.

3. You have to check your mainboard manufacturer's website but the hardware you have and the SATA specification has a couple of years in between so I don't believe that your motherboard manufacturer has published a BIOS update.

If you want to resurrect your PC with Linux, I suggest you to keep it as a gateway computer to your home network and configure it to act as an

1. Antivirus,
2. E-mail,
3. Network,
4. Proxy server.

It will be able to handle a small home-networking traffic with the specifications but will not be able to keep up with today's demanding applications.

I have an old 486 generation CPU
I have an old 486 CPU, but it's AMD CPu, here's the specs:

AMD Am 5x86 133 - P75 (though it's an AMD CPU but it's fit in the Intel 486 socket)
SYL8884 (support PCI 2.0, ISA, 2 IDE Port, LPT, Serial, 2 72 pins slot memory)
32 MB EDO Ram
Intel Dual Port Server Adapter (PCI)
MPEG2000 (ISA)
FM Radio Forte (ISA)
4 ports PCI USB (works only 1 port, because troubled with the Win 95 IRQ settings) (PCI)
ATi Rage All In Wonder 4 MB (but i don't know how to set up the TV function) (PCI)
6.4 GB HDD
24x Samsung CDROM
1.44 FDD
1.2 FDD

1. Until now, i have only use MS DOS and Windows 95 B. Is there any Linux distro which can be installed on 486 machine that support USB devices without installing the USB device driver? Automatic detection just like WIndows ME or XP.

2. And, if i put MPEG2 DVD Decoder PCI Card + DVD-Drive on my machine, will it be able to play DVD Movie?

3. How to reprogram the BIOS, so it can detect new hardware devices like SATA drive? do i have to use dissasembler?
