Ultra Wide SCSI host adapter driver
SYNOPSIS
adw* at pci? dev ? function ?

DESCRIPTION
The
adw driver provides support for the ADW (AdvanSys)
ABP-940UW, ASB-3940UW, ASB-3940U2W SCSI host adapters.
The following kernel configuration options are available:
- options FAILSAFE
- Disables tagged command queuing, wide data transfers and
synchronous data transfers for all SCSI devices controlled by the
adw driver. By default, tagged command queuing, wide
data transfers and synchronous data transfers are used if the SCSI devices
support them.
The following options use a mask to specify which SCSI
peripherals the option applies to. The mask is a 16 bit
bitfield value. Each bit corresponds to a peripheral ID. The LSB (bit 0)
corresponds to the peripheral with ID 0. The MSB (bit 15) corresponds to
the peripheral with ID 15. The following features cannot be disabled for
the host adapter, which by default has ID 7.
- options SCSI_ADW_WDTR_DISABLE=mask
- Disable WIDE data transfer for the peripherals specified
by the mask value.
- options SCSI_ADW_SDTR_DISABLE=mask
- Disable SYNCHRONOUS data transfer for the peripherals
specified by the mask value.
- options SCSI_ADW_TAGQ_DISABLE=mask
- Disable TAGGED COMMAND QUEUING for the peripherals
specified by the mask value.
