Works fine on my rev 1A mobo. Though I did have problems getting it to work. Cant remeber what the issues were as was few years ago, but I rember couldn't get it to work. I seem to remeber that I ended up disregarding what you were supposed to have the jumpers on for blizzard cards.
Just remove all jumpers. have them all open. Worked for me anyroad. I ve got a manual somewhere, but wont be able to dig it out at mo.
Had it working with blizzard 1230 mk IV and a blizzard ppc
Hope this helps
