What the error means is that the graphics aren't installed for Bochs, so all it can do is text. There are several ways to fix it:

If you have a mac, you need to get a binary of the program (easier than building anyways). Get it at: http://www.macupdate.com/info.php/id/11177 or I'm pretty sure theres a version of bochs on MacPorts.

If you're on Linux (especially Ubuntu), there is a package with the x libraries installed already. I'm pretty sure the package is called bochs-x, or something similar to that.

If one of those doesn't work, let us know and we can help more.

Just remove address=0xf0000 from bochsrc.txt.
