Which dowload to use for Red Hat 7.2 i586?

[Jerome]

I see downloads for i386 and i686.  My machine is i586.  Which binary
should I use?  Do I need to download source and compile for my
machine?  Or is there an available binary somewhere?

Environment:
Red Hat Linux release 7.2 (Enigma)
Kernel 2.4.17d on an i586

Regards,

Jerome
