BHA(4)                   BSD Kernel Interfaces Manual                   BHA(4)

NAME
     bha -- Buslogic SCSI interface

SYNOPSIS
     bha0 at isa? port 0x330
     bha1 at isa? port 0x334
     bha* at pci?

DESCRIPTION
     The bha driver supports the following Buslogic SCSI adapters:

           Buslogic ISA BT-445
           Buslogic EISA BT-74x
                   (supported in ISA compatibility mode only)
           Buslogic PCI BT-9[45][68]

SEE ALSO
     cd(4), ch(4), intro(4), isa(4), pci(4), scsi(4), sd(4), st(4), uk(4)

HISTORY
     In OpenBSD 3.0 and earlier, this driver was named bt but was renamed to
     bha in later releases.

BUGS
     The Buslogic BT-930 is not supported in this driver.

     The Buslogic BT-445S has a problem in early hardware and firmware revi-
     sions 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.
