FreeDOS 1.3 Installer does not work with VIA C3 processor ("invalid opcode" messages)

I actually filed this bug here https://gitlab.com/FreeDOS/OS/FDI/-/issues/10 but come to think of it, should I have filed it here on Github instead? All relevant info is there on Gitlab. There is a comment about certain assembly instructions maybe not being available on all cpus as well.
