In Part 3 I mentioned my file system was Read only. On this installation, I did not make any changes to the default configuration files and my file got configured as read-write, allowing me to continue the Arch Linux install. As a guess I would say the Read only file system problem was caused by the noatime line in the fstab file. I had followed this under the fstab instructions:
Note: The 'noatime' option disables writing read access times to the metadata of files and may safely be appended to / and /home regardless of your specified filesystem type for increased speed, performance, and power efficiency (see here for more).
The next thing I had trouble with was the touchpad, which did not work when I tested X. Then I tried to configure Xorg to see if that would help. When I started X this time I got a blank screen. So got rid the X11 directory and tried again. This brought me back to where I had started, Xterm showed up in the upper left corner but no response from keyboard or touchpad. After much frustration I found a usb mouse, plug it in, started x and the mouse worked. At this point the touchpad was still useless.
After installing a Desktop Environment (LXDE), I started X and the desktop loaded with out any problems. Now I have a base system with a trackpad that does not work, no wireless, and no applications.
I now know a little about Arch Linux. If you decide to try Arch make sure you have lots of time and patience and follow the wikis.
