A bleeding-edge distro isn't a good fit for your equipment. They dropped IA32 support long ago, for example. And there are plenty of alternatives. RHEL8 will be supported until 2029. RHEL9 will be supported several years longer, and as it is currently in beta it is unlikely to adopt these BIOS deprecation changes from Fedora. Come 2030+ it might be time to retire your ancient equipment, or relegate it to legacy/contemporary OSes.
