Page: 31 / 64

Chapter 3. Using IBM Fast!UTIL
This chapter provides detailed configuration information for advanced users who
want to customize the configuration of the FAStT FC2-133 Adapter and the
connected Fibre Channel devices. You can configure the adapter using the
Fast!UTIL utility.
Starting Fast!UTIL
To access Fast!UTIL, press Ctrl+Q during the adapter BIOS initialization (it might
take a few seconds for the Fast!UTIL menu to display). If you have more than one
FAStT FC2-133 Adapter, Fast!UTIL prompts you to select the adapter you want to
configure. After changing the settings that are described in the “Configuration
Settings menu options” section, Fast!UTIL restarts your system to enable the new
parameters.
Important: If the configuration settings are incorrect, your FAStT FC2-133 Adapter
will not function properly. Do not modify the default configuration settings unless you
are instructed to do so by an IBM support representative or in the installation
instructions.
Configuration Settings menu options
The options described in this section configure the Fibre Channel devices and the
FAStT FC2-133 Adapter to which they are attached. The Configuration Settings
menu displays several options that you can use to configure your adapter.
Host Adapter Settings
You can access this option from the Configuration Settings menu in Fast!UTIL by
selecting
Host Adapter Settings . The current default settings for the host adapter
are listed in Table 2 and are described in this section. You can modify the default
host adapter settings that are listed in Table 2.
Table 2. Modifiable host adapter default settings

Host adapter BIOS: When this option is set to Disabled, the read-only memory
(ROM) BIOS code on the FAStT FC2-133 Adapter is disabled, freeing space in
upper memory. You must enable this setting if you are starting your operating
system from an external Fibre Channel hard disk that is attached to the FAStT
FC2-133 Adapter. The default is Disabled.
Frame size: This setting specifies the maximum frame length supported by the
FAStT FC2-133 Adapter. The default size is 2048. If you are using F-Port
(point-to-point) connections, use the default for maximum performance.
