Host adapter BIOS: When this setting is disabled, the ROM
BIOS on the Netfinity Fibre Channel PCI Adapter is disabled,
freeing space in upper memory. The default is Disabled.
Ÿ
Enable LUNs: When this setting is yes, multiple logical unit
numbers (LUNs) are supported. When this setting is no,
multiple LUNs are not supported. LUN support is typically
required for CD-ROM changers or redundant array of
independent disks (RAID) boxes that use LUNs to map drives.
The default is Yes.
Ÿ
Execution throttle: This setting specifies the maximum number
of commands executing on any one port. When a port's
execution throttle is reached, no new commands are executed
until the current command finishes executing. The valid options
for this setting are: 1, 4, 8, 16, 32, 64, 128, and 255. The default
is 255.
Ÿ
Drivers load RISC code: When this setting is enabled, the host
adapter uses the RISC firmware that is embedded in the device
driver. When this setting is disabled, the device driver loads the
latest version of RISC firmware found on the system. The
default is Enabled.
