Appendix A. Fast!UTIL
This appendix provides detailed configuration information for advanced users who
want to customize the configuration of the IBM FAStT Host Adapter and the
connected devices. You can configure the adapter using the Fast!UTIL utility.
Access Fast!UTIL by pressing Alt+Q during the adapter BIOS initialization (it might
take a few seconds for the Fast!UTIL menu to appear). If you have more than one
IBM 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 IBM FAStT Host Adapter
will not function properly.
Each host adapter has a unique serial number. Take a minute to write down the
serial number of the FAStT Host Adapter. In the event that the nonvolatile random
access memory (NVRAM) is damaged (see “Scan Fibre Channel devices” on
page 28), you will be prompted for the IBM FAStT Host Adapter serial number.
Fast!UTIL options
This section describes the Fast!UTIL options.
Configuration settings
This is the first option on the Fast!UTIL Options menu. These settings configure
the Fibre Channel (FC) devices and the IBM FAStT Host Adapter to which they are
attached.
Host adapter settings
You can access this option from the Configuration Settings menu. The current
default settings for the host adapter are listed in Table 1 and are described
immediately following the table.
Note: The host adapter settings and default values will vary, based on the version
of BIOS code installed for the adapter.
Host adapter BIOS: When this option is set to Disabled, the ROM BIOS on
the IBM FAStT Host Adapter is disabled, freeing space in upper memory. The
default is Disabled.
