Ew, old-style PIO master/slave used for ATA DMA (not recommended). Furthermore, you're using your newer devices as slaves, so they are stuck with the ATA support of their masters. Lastly, you're using different vendors for the disks -- IBM (and WD drives, who OEM'd IBM drives at that time) had numerous issues with the ATA logic Intel ICH and ViA 82xx southbridges. -- Bryan J.
