most of the cards worked for me. The exception to the rule was a Buddah Flash. Although it is listed as a working card in the manual nothing made it work.
it seems you must be carefull on your combination of cards. in my example i had also an apollo 1240, PIV, X-Surf, IDE-fix Express and i think the Apollo caused the problems (it is not a recommended accell cards for the micronik board, but it was to expensive to change my accel cards just for the sake of it) so i continued to use my IDE-fix Express instead.
