v Exit FASt!UTIL
You can access the host bus adapter settings through the Configuration Settings
menu in Fast!UTIL. See "Host bus adapter settings" and"Advanced FC 4Gbps
PCI-X Adapter Settings" on page 25 for detailed information on the settings.

Host bus adapter settings

You can modify most of the host bus adapter settings. The current default settings
for the host bus adapter are listed in "Advanced FC 4Gbps PCI-X Adapter Settings"
on page 25. These settings are described following the table. You can modify the
following default host bus adapter settings.

IBM System Storage DS4000 FC 4Gbps PCI-X Single/Dual Port HBA: Installation and User's Guide
The BIOS address is the I/O address where the BIOS code is stored when
you press Ctrl+Q or when you have the BIOS code enabled for starting
from the root directory. This is the address of the BIOS code in ROM
shadow memory. Multiple adapters can be installed in the server, but only
one BIOS instance is loaded for all of the adapters.
Note: The BIOS code is loaded from the first port of the first adapter that
the server recognizes. This code is used for all remaining DS4000
FC 4Gbps PCI-X Single Port and DS4000 FC 4Gbps PCI-X Dual
Port adapters in the same bus or server. The level of BIOS code that
is loaded does not affect other adapters with earlier BIOS code
levels.
The BIOS revision is the revision number of the BIOS code that is loaded
from the first FC 4Gbps PCI-X Adapter that the server recognizes. Each FC
4Gbps PCI-X Adapter in the server has the same BIOS code revision
number because only one BIOS code instance is loaded.
The adapter serial number is located on the noncomponent side of the
adapter. See Figure 1 on page 3 for the location of the serial number label.
The interrupt level is the interrupt that is used by the FC 4Gbps PCI-X
Adapter. The interrupt level can change when the operating system is
installed.
This is the worldwide port name.
When this setting is Disabled, the ROM BIOS on the FC 4Gbps PCI-X HBA
is Disabled, freeing space in upper memory. This setting must be Enabled if
you are booting from fibre channel disk drive attached to the PCI-X board.
The default is Disabled.
This setting specifies the maximum frame length supported by the FC
4Gbps PCI-X HBA. The default size is 2048, which provides maximum
performance for F-Port (point-to-point) connections.
After resetting the loop, the firmware refrains from initiating any loop activity
for the number of seconds specified in this setting. The default is 5
seconds.
