### NAME

bha, bt - Buslogic SCSI adapter driver

### SYNOPSIS

bha0 at isa? port 0x330 irq ? drq ? bha* at eisa? slot ? bha* at pci? dev ? function ? scsibus* at bha?

### DESCRIPTION

The bha driver supports the following Buslogic SCSI adapters:

Buslogic ISA BT-445
Buslogic EISA BT-74x
Buslogic PCI BT-9[45][68]

### SEE ALSO

cd(4), ch(4), intro(4), scsi(4), sd(4), st(4)

### HISTORY

In NetBSD1.2 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 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.
