China DOS Union

Because it's a computer for controlling a tower clock from more than ten years ago, so it's still a very old pure DOS computer. Recently, the motherboard was burned out, and a new host was replaced, and the original hard drive and sound card were installed back. As a result, it prompts that the sound card driver is not found. Asking all the experts, how to set it?

The mainboard is broken, and a new host is replaced. Then are the configurations of the two hosts completely the same? If the sound cards are different, then the driver of that sound card is still on the hard disk of the original host, and the relevant configurations are also written in the CONFIG.SYS and AUTOEXE.BAT of that host.
