How to play doom?

[Mark Par <markp@ispbonanza.com.ph>]

Hi,

When I start lxdoom (lxdomm -iwad AXE.WAD) I get a message like this

LxDoom v1.4.4 (http://lxdoom.linuxgames.com/)
Z_Init : Allocated 6016Kb zone memory
 found AXE.WAD
IWAD found: AXE.WAD
IWAD tag not present: AXE.WAD

I even tried to use the file boomlump.wad that is included in the distribution and I get the same results.

How can I play DOOM?
