     trollers chips:
           -   53c810, 53c810a and 53c815 (fast scsi)
           -   53c820, 53c825 and 53c825a (fast wide scsi)
           -   53c860 (ultra scsi)

BUGS

     This driver is still being worked on, some features are not used and per-
     formances are not optimal. However it appears to be more robust than the
     ncr(4) driver.
