Appendix F. Fast!UTIL options
This appendix provides detailed configuration information for advanced users who
want to customize the configuration of the FAStT Host Adapter and the connected
devices. However, customizing the configuration is not recommended, as the
adapter was configured specifically for the Model 326.
The board can be configured using Fast!UTIL. Access Fast!UTIL by pressing Alt +
Q during the adapter BIOS initialization (it may take a few seconds for the
Fast!UTIL menu to appear). If you have more than one FAStT Host Adapter,
Fast!UTIL prompts you to select the adapter you want to configure. After changing
the settings, Fast!UTIL restarts your system to load the new parameters.
Attention: If the configuration settings are incorrect, your FAStT Host Adapter
board might not function properly.
Configuration settings
This is the first selection on the Fast!UTIL Options menu. These settings configure
the Fibre Channel (FC) devices and the FAStT Host Adapter to which they are
attached.
Host adapter settings
From the Configuration Settings menu in Fast!UTIL, select Host Adapter Settings .
The default settings for the FAStT Host Adapter are listed in Table 33 and described
in the following paragraphs.

This setting specifies the maximum frame length supported by the FAStT
Host Adapter. The default size is 1024. If using F-Port (point-to-point)
connections, change this setting to 2048 for maximum performance.
Loop Reset Delay
After resetting the loop, the firmware does not initiate any loop activity for
the number of seconds specified in this setting. The default is 5 seconds.

Hard Loop ID setting. The default is Disabled.
