The bha driver supports the following Buslogic SCSI
  adapters:
  - Buslogic ISA BT-445
-  
- Buslogic EISA BT-74x
-  
- Buslogic PCI BT-9[45][68]
-  
 
In NetBSD 1.2 and earlier, this driver was named
  bt but was renamed to bha in
  later releases.
The Buslogic BT-930 is not supported in this driver.
The Buslogic BT-445S has a problem in early hardware and firmware
    revisions which prevents proper operation on a system with more than 16MB of
    RAM. Hardware revision D and firmware revision 3.37 should be considered
    minimum requirements for using this board on systems configured in this
    manner.
