Q
n RIO Operation Mode. This setting specifies the reduced operation (RIO) modes,
if supported by the software driver. RIO modes allow posting multiple command
completions in a single interrupt (see table 14-4). The default is 0.
n Interrupt Delay Timer. This setting contains the value (in 100-microsecond
increments) used by a timer to set the wait time between accessing (DMA) a set
of handles and generating an interrupt. The default is 0.
n Enable BIOS Memory Map I/O. When this setting is Yes, the BIOS accesses
the QLA23xx through memory cycles. When this setting is No, the BIOS
accesses the QLA23xx with I/O cycles. The default is No.

Scan Fibre Channel Devices
This option scans the FC loop and lists all the connected devices by loop ID.
Information about each device is listed, for example, vendor name, product name,
and revision. This information is useful when configuring your QLA23xx HBA and
attached devices.
14.4
Fibre Disk Utility
This option scans the FC loop and lists all the connected devices by loop ID. You
can select a hard disk and do one or more of the following:
n Perform a low-level format
n Verify the disk media
n Verify the disk data
n Select the next drive
CAUTION!
Performing a low-level format destroys all data on the hard disk.

Loopback Data Test
This test uses the Diagnostic Loopback mailbox command to send and receive data.
The Fibre Channel port must be active or a loopback connector must be installed
before running this test.
Table 14-4. RIO Operation Modes
Option Operation Mode
0 Interrupt for every I/O completion
5 Interrupt when interrupt delay timer expires
6 Interrupt when interrupt delay timer expires or no active I/O
