The last time I tried it was with a 2.4.10 kernel on an ASUS KG7 with 1.4GHz AMD Thunderbird and it worked without problems. > I've started tinkering with the source, but it's very difficult to > make progress as the driver is the only documentation I have.

(at the level > of detail where it would be possible to maintain the driver) We got one datasheet (under NDA) which did not go into much detail, at least not nearly enough to write a driver. To write the driver Visiontech gave us the Windoze NT sources and some support over e-mail. Ralph
