bhaBuslogic SCSI interface

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

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]

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

In OpenBSD 3.0 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.
