I got an old Dell Dimension 4600 for free and I want to get Linux on it. Ubuntu not required, but it's what I have running now.

lspci -v tells me:

Ethernet Controller: Intel Corporation 82562EZ 10/100 Ethernet Controller (rev 02)

Subsystem: Dell Device 0174

Flags: bus master, medium devsel, latency 64, IRQ 20

Memory at fbfff000 (32-bit, non-prefetchable) [size=4K]

I/O port sat df40 [size=64]

Capabilities: <access denied>

Kerneldriver in use: e100

This is without modifying anything. I'm surprised the driver that came with Ubuntu didn't work.

Intel provides a Linux driver here:

But when I try to make install I get an error, which is addressed in the README:

Driver Compilation

  ------------------



  When trying to compile the driver by running make install, the following

  error may occur:



      "Linux kernel source not configured - missing version.h"



  To solve this issue, create the version.h file by going to the Linux

  source tree and entering:



      make include/linux/version.h.

What do they mean go to the Linux source tree? I didn't get an /include/ directory in the tarball.
