Red Hat 9 was almost impossible to run decently on an i386-class machine
due to lack of resources (mainly, the CPU). I sill have a 386DX/20 lying
around, but it's simply unable to run anything newer than a 2.0, or
2.2-kernel based distribution.

As I said before, EnGarde Secure Linux 1.0, which is 2.2-kernel-based,
is what that machine can run at most.

I like this one. Go for it!
