>4 GByte Addressing.
Enable this option if the system has more than 4 GB of memory available.
The default is Disabled.
LUNs per Target
Specifies the number of LUNs per target. Multiple LUN support is typically
for redundant array of independent disks (RAID) boxes that use LUNs to
map drives. The default is 0.
Enable LIP Reset
Determines the type of loop initialization process (LIP) reset that is used
when the operating system initiates a bus reset routine. When this setting is
yes, the driver initiates a global LIP reset to clear the target device
reservations. When this setting is No, the driver initiates a global LIP reset
with full login. The default is No.
Enable LIP Full Login
Instructs the ISP chip to log in to all ports after any LIP. The default is Yes.
Enable Target Reset
Enables the drivers to issue a Target Reset command to all devices on the
loop when a SCSI Bus Reset command is issued. The default is Yes.
Login Retry Count
Specifies the number of times that the software tries to log in to a device.
The default is 30 retries.
Port Down Retry Count
Specifies the number of times the software retries a command to a port
returning port down status. The default is 30 retries.
Drivers Load RISC Code
When this setting is enabled, the host adapter uses the RISC firmware that
is embedded in the software driver. When this setting is disabled, the
software driver loads the RISC firmware found on the system. The default is
Enabled.
Note: The driver being loaded must support this setting. If the driver does
not support this setting, the result is the same as disabled regardless
of the setting. Leaving this option enabled guaranties a certified
combination of software driver and RISC firmware.
Enable Database Updates
When enabled, it allows the software to save the loop configuration
information in flash memory when the system powers down. The default is
No.
Note: This option usually applies to Windows NT and Windows 2000
operating environments.
Disable Database Load
When enabled, the device database is read from the Registry during driver
initialization. When disabled, the device database is created dynamically
during driver initialization. The default is No.
IOCB Allocation
Specifies the maximum number of buffers from the firmware's buffer pool
that are allocated to any one port. The default is 256 buffers.
