Dosraider: It's easy to forget that some knowledge we consider basic and take for granted isn't either of those for the average PC user - and at some point wasn't such for us either.
G Mann: Sorry, I assumed you were familiar with multi-part RARs. My fault.
Okay, those *.rxx files you have are segments of a multi-part RAR archive. You need a dearchiver such as 7Zip (
http://www.7-zip.org/) to unpack them (there are others, but 7Zip is completely free). The .rar file is the "main" file for the multi-part archive (DW21.rar and DW22.rar), and that's the one you'll open with 7-Zip and unpack the contents; the program will automatically unpack the contents of the remaining segments of the multi-part archive.
Ermuli has used ECM on the discs - it's another form of compression used to reduce the size of the image before it's compressed further with RAR. You need to unpack one of the discs at a time, then run the UNECM.BAT file that comes with the other archive contents and wait until it finishes uncompressing the image. This will give you a CloneCD image of the respective disc.
Do that for both DW21.rar and DW22.rar (not neccesarily in that order, but unpack and UNECM whichever image you start with before following with the other).
Now you have the CloneCD images of both discs. They're comprised of several files, but we're interested in the ones with IMG extension. Those are the files we'll use in IMGMOUNT (replace the paths and filenames in the command given in my previous post with the locations and names of those two files, it's a good idea to put the location and name of the first disc earlier than that of the second - just for convenience).
As explained in the tutorials, you'll also need to have a C mount in DOSBox. Check DOSRaider's guide if you haven't gotten to that part yet.

Now, you should have DOSBox running with a directory on your HDD mounted as its' C drive and the images of both Discworld 2 CD's mounted as your D drive.
I don't have a copy of the discs on my HDD right now, so for the moment I can only give you general advice on what to do next (getting a copy as I speak).
Switch to the DOSBox D drive by typing:
d:
Next, the game files have to be installed to the virtual C drive. There will be an executable on the disc named
setup or
install so try entering each of those as a command. If the installer doesn't start after that, you'll need to enter the following:
dir *.exe
dir *.com
dir *.bat
To get a list of all executable files in the CD root and try running them.
When the installer runs, it will most likely query you where to install the game - should be defaulting to C:\DW2 , if not then that's what you want to set it to.
If you are asked for any of the following, here are the correct values:
Sound Card or anything to do with audio / music etc:
* Pick the last Sound Blaster version on the list (16 is best, then Pro 2 or "Pro (new version)", then Pro, then 2, then "plain" Sound Blaster)
IRQ (Interrupt): 7
DMA: 1
Address: 220
After the installation completes, you need to replace the dwb.exe with the patched version. To do that (in Windows), open the directory you've set as DOSBox' default C drive, open the DW2 subdirectory and unpack the patched dwb.exe there. You will be asked if you want to overwrite the original file - confirm. At this point, the game is ready to start in DOSBox.
To run the game in DOSBox, you need to get to the C drive if you're not already there ( type
c: ), then to the DW2 directory if not already there (
cd c:\DW2 ) then run the game by either
dw2 or
dwb .
