In our case, our first Linux port, from SCO Openserver, targeted  
Redhat 7.1 on these platforms, where money wasn't available to  
upgrade much of the older computers.  We also target newer computers,  
which had the disadvantages that the obsolete version of SCO we were  
using didn't support many of the newer features, such as PCMCIA.

Redhat 7.1 worked fine for a couple versions, then Redhat decided to  
drop support for their non EL distributions, and it was determined  
that RHEL 2.1 was a relatively easy port, since it was based on 7.2,  
and had security support without having to do the security patches  
ourselves.

Now, there is a desire to support an accredited OS, which essentially  
requires either a version of Suse, or Redhat 3 or later.

So that is how you can get into a Enterprise level OS for obsolete  
hardware :)

I also can understand why a company like Redhat won't support old  
hardware like this out of the box.  Who cares, in the enterprise  
realm, whether Redhat can provide the fastest web server on 486, when  
you can buy 3 gigahertz computers with 1 gig or more RAM for as cheap  
as they are nowadays in more widely available platforms.  By not  
supporting it, Redhat doesn't have to test, keep all these  
configurations around, etc.

This is kind of an issue on the LKML right now.  Not 486's, but  
trying to support large workloads on 32 bit computers when people can  
go to 64 bit CPUs, for example, where many of the limitations go away.
