IBM TotalStorage DS4000 FC2-133 Dual Port Host Bus Adapter: 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
FC2-133 Single Port and DS4000 FC2-133 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 DS4000 FC2-133 that the server recognizes. Each DS4000
FC2-133 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 3 on page 4 for the location of the serial number label.
The interrupt level is the interrupt that is used by the DS4000 FC2-133. 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 FC2-133 HBA is
Disabled, freeing space in upper memory. This setting must be Enabled if
you are booting from an fibre channel disk drive attached to the FC2-133
board. The default is Disabled.
This setting specifies the maximum frame length supported by the FC2-133
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
This setting forces the adapter to attempt to use the ID specified in the
Hard Loop ID setting. The default is Enabled.
If the Adapter Hard Loop ID setting is Enabled, the adapter attempts to use
the ID specified in this setting. The default ID is 125. You should set this ID
to a unique value from 0-125 if there is more than one adapter connected
to a FC-AL loop and the Adapter Hard Loop ID setting is Enabled.
