Yep, running that command gave me this:

Disk /dev/sda: 14593 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

   Device Boot Start     End   #cyls    #blocks   Id  System
/dev/sda1          0+      7       8-     64228+  de  Dell Utility
/dev/sda2          8     660     653    5245222+   b  W95 FAT32
/dev/sda3   *    661   14020   13360  107314200   83  Linux
/dev/sda4      14021   14592     572    4594590    5  Extended
/dev/sda5      14021+  14592     572-   4594558+  82  Linux swap / Solaris

So I do have a swap but why are sda4 and sda5  both looking like they start 
and end at the same location?   I so far have not found a way to edit 
fstab, ...well I CAN edit it, but I can't save it.

I'm pretty poor at complaining, usually I get to listen to them not make 
them!! ;)
