I've never yet seen an ASUS board that played nice with Windows 9x. As far as I know they use AMI BIOS as well, not AWARD, which is more 9x friendly. But some members here use ASUS, so I guess it depends on personal preference and the luck of the draw. I prefer Gigabyte first and then MSI. Not had much experience with ASRock or others.When you look at the specs for the motherboard you choose, be sure to check the exact brand and specs of the LAN controller. Certain RealTek and Marvell chips have 9x drivers, but not all. If it is Intel, then forget it, they dropped 9x support ages ago. It's possible to get a 9x compatible LAN controller, but there's no getting around the sound issue. You will either need a 9x compatible PCI sound card or a "USB Audio" device which I have no experience with.Iv found a few boards I like but of course they have intel nic. However the boards use intel 1218v and after googleingni found a drivers page with the drivers for dos.https://downloadcenter.intel.com/product/71305/Intel-Ethernet-Connection-I218-V
