I found this motherboard, circa 2006 tualatin celeron 1.2, i815. I’m hoping to get a pci sound card working in dos. Interesting bios options. Any thoughts or suggestions? Only pci sound card I own right now is a cheap generic cmi8738 and from what I’ve read, ess solo 1 pci cards have the best chance of working in dos. Most likely going to pick up a used one on eBay. I’ve done no other tinkering so far other than installing dos 6.22
