Hi,
First, don't follow the above instructions unless you want to create a pile of 3.5" floppy disks and play toaster for about an hour. There's an easier way to install Fixpaks right off the hard disk.
Since you're warp 3 (not warp server) you might want to stick with Fixpak 40.
Fixpaks 41 and 42 were technically only for Warp Server 4, which was based on the Warp 3 codebase plus all the LAN stuff. Without hacking your syslevel files Fixpak 41 and 42 usually don't install on a Warp 3 machine, but 40 works well. Some people have had luck with FP42 on their Warp 3 machines, some people have experienced grief. However 40 generally works for all who have tried it on Warp 3.
To install directly off your hard disk, first grab FP40. The easiest way to install it is from the RSU version of the fixpak. From IBM's ftp site grab all the files:
ftp://service.boulder.ibm.com/ps/products/os2/rsu/xr_w040/unzip all the xr_w040x.zip files into their own folder (say, c:\fp40 as an example)
Unzip the csf143.zip into its own folder (for example, I usually put it into c:\os2serv )
You do not need the fpinstl.zip file for this method of installing fixpaks! It was used in the older web-based RSU install, but we don't need that file anymore (IBM doesn't even support the web-based install any more, so we do the steps manually)
Create yourself an archive directory for the FP backout files
md c:\archive
Change to your c:\os2serv directory, and from a command prompt, run:
os2serv c:\os2serv\csf c:\fp40
Eventually the Fixpak install tool will pop up. Click on the fixpaks to install and click install.
That's pretty much all you need!
