Using the Shared Interrupts Option
Command line option:
sharedint=<option>
Default value:
disable
Valid options:
enable, disable
Function:
Supports shared interrupts
Possible Impact:
Enabling may cause a performance
degradation.
Applicable Versions:
3.04.00 and higher
The shared interrupt option should be enabled any time a PCI card
other than NCR Host Adapters are added to a system which
assigns all PCI cards the same interrupt value. The added card
must be able to support shared interrupts. The driver automatically
handles the case of more than one NCR host adapter sharing an
interrupt.
Using the Wide SCSI Option
Command line option:
wide=<option>
Default value:
enable
Valid options:
enable, disable
Function:
Enable/Disable support of Wide SCSI.
Possible Impact:
No Wide SCSI Support available.
Applicable Versions:
3.04.00 and higher
This option specifically allows the user to disable support of wide
SCSI when using a wide SCSI controller. This option should be set
to “disable” if a wide SCSI device is present on the system, but a
narrow SCSI cable is connected somewhere on the bus between
the wide SCSI host adapter and the wide device, thus prohibiting
the transfer of wide data. If this option is set to “disable”, the wide
device may still be used, but all data transferred to/from the device
will be narrow (8 bit). The driver will not initiate a wide SCSI
transfer request negotiation.
