.Nd Adaptec SCSI host adapter driver
|
|
.Sh SYNOPSIS
|
|
.Cd device "aha0 at isa? port ? cam irq ? drq 5"
|
|
.Cd device scbus0 at aha0
|
|
.Sh DESCRIPTION
|
|
This driver provides access to the
|
|
.Tn SCSI
|
|
bus connected to an Adaptec 154xA, 154xB, 154xC, 154xCF, or 154xCP
|
|
host adapter. Host adapters supporting a 154X compatible interface,
|
|
such as some Tekram controllers and the Adaptec 174x in 154x
|
|
emulation mode can, also be attached with this driver. For optimum
|
|
performance, Adaptec 174x controllers should be configured in
|
|
enhanced mode and attached via the
|
|
.Xr ahb 4
|
|
driver.
|
|
.Pp
|
|
One kernel config entry for every card to be attached by the system is
|
|
required. Specific values for the port address, irq, and drq may be
|
|
specified. If wildcard values are used, the driver will query the
|
|
device for its current settings and use those. If the port address
|
|
is a wildcard, the driver consults an internal table of possible port address
|
|
locations and attaches to the first unattached card it finds. The possible
|
|
port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and
|
|
0x134.
