When you download the Apache software for SCO Open Server 5 from SCO, it comes as a custom package named apache-1.3.0-VOLS.tar. (this is the current version as of this writing on August, 1998). This simply means that the software can be installed using SCO's custom command.
The initial installation will require about two megabytes of disk space.
The software will be installed in a directory named /usr/local/lib/apache.
