In the cIOS pack in chapter 2 cIOS248 is included. It should have installed in the first place so that means you got an error and continued the guide without addresing the error. This is not good to do....if this IOS was more important you could be in a load of trouble right now.
Get the cIOS248 wad from the cIOS pack download and install it with MMM.
Edit: You are also missing 247??
