I cannot find out what motherboard this is. Its an old one but it works. The BIOS says IBM so it must be from an OEM machine but what machine? If anyone could find out what motherboard this is or what machine it came from that would be greatly appreciated. It says (C) IBM '98 so its from that era. I tried to get the pictures as clear as I could. Here are the images. https://imgur.com/a/QaogwNM
