A – Fast!UTIL Configuration Settings
DC8151101-00 C A-3
❑ Safe. All optimal configuration settings are disabled and all attached
devices work in minimal configuration (narrow, asynchronous mode).
NOTE: Safe mode is primarily for troubleshooting SCSI devices that
are not functioning properly during normal system operation.
■ Drivers Load RISC Code. When this setting is Enabled, the QLA12160
board uses the RISC firmware that is embedded in the software driver. When
this setting is Disabled, the software driver loads the latest version of RISC
firmware found on the system. The default is Enabled.
NOTE: The driver being loaded must support this setting; otherwise, the
result is the same as Disabled regardless of the setting. Leaving
this option Enabled guarantees a certified combination of software
driver and RISC firmware.
■ >4 Gbyte Addressing. Enable this setting when your system has more
than 4 GB of RAM available. The default is Disabled.
■ Fast Command Posting. When this setting is Enabled, command execution
time is decreased by minimizing the number of interrupts. The default is
Enabled.

SCSI Device Settings
After changing the host adapter settings for the QLA12160 board, you can modify
device parameters for SCSI devices connected to the board. From the
Configuration Settings menu in Fast!UTIL, select SCSI Device Settings. The
settings are linked to the device’s SCSI ID (0–15). If you make changes, be sure
that the SCSI ID matches the settings of the device you want to change. Select
Scan SCSI Bus from the Fast!UTIL Options menu to see the SCSI IDs assigned
on your system (see section A.3).
NOTE: The Adapter Configuration setting in the Host Adapter Settings (see
section A.2.1) controls which device settings you can change.
The options and defaults for SCSI device settings are listed in table A-2 and
described in the following paragraphs.
