The 1542b *is* a good controller, since it's a DMA master. Just verify that your motherboard can correctly handle the demands that high-speed DMA places upon the system. The problems folks have are *not* with the 1542b, but with other parts of their systems. For instance, the recent post complaining that their floppy no longer works-- well, I'll bet the person didn't read the Fine manual :). Since the 1542b has an on-board floppy controller that by default, shows up as controller zero, by just plugging the 1542b in with factory default jumper settings, the floppy controller on the 1542b is overlapping the existing floppy controller already installed in their system. Thus, a no longer working floppy being blamed on the Adaptec controller. --Steven
