I'm using a KT7-RAID with a SBLive Value with absolutely no problems. When I migrated my system, Win98SE detected every piece of hardware perfectly and I didn't have any problems at all with the drivers.
You have, I assume, started out with a clean system (preferably a blank hard drive and new installation of WindowsXX, but a previous installation with all items deleted from the Device Manager will do)? Start with only the video card installed, get all of its drivers functioning, then go on to install the sound card and all of its drivers, then NIC, then any additional cards, making sure there are no conflicts at each step.
