I would be interested, though, to here what Tyan's tech support says. Maybe you should write them and ask, and post the reply here. I've always thought that UDMA was impossible unless bus mastering drivers were installed, but Win98 may include them. (My box doesn't seem like it has DMA enabled right now - I had trouble installing the bus mastering drivers, so I omitted them, and I'm running 98.) -Peter Ramins The PCBUILD web site always needs good submissions.
