Does anyone have an alternate implementation idea for DELAY so that it is cpu/bus independant? I just tracked down the problem with the aic7870 based cards, and it turned out that what should have been a milisecond delay was so short on this P-90 system that I repolled the controller's interrupt register before it had enough time to clear from the last interrupt! The other interresting thing is that the on- board aic7870 on this motherboard never had problems with the driver. The chips were made in separate plants, but have the same revision number, but I guess it could be a buggy chip that is accentuating this problem. __ Justin T.
