FC1142SR and FC1242SR DC 4Gb PCI Express host bus adapters for Linux and Windows installation guide 27
A description of each setting follows:
• Host Adapter BIOS—When this setting is disabled, the ROM BIOS on the HBA is disabled,
freeing space in upper memory. This setting must be enabled if you are booting from an Fibre
Channel hard disk connected to the HBA. The default is Disabled.
• Frame Size—Specifies the maximum frame length supported by the HBA. The default 2048
provides maximum performance for F_Port (point-to-point) connections.
• Loop Reset Delay—After resetting the loop, the firmware refrains from initiating any loop
activity for the number of seconds specified by this setting. The default is 5 seconds.
• Adapter Hard Loop ID—Forces the HBA to attempt to use the ID specified in the Hard Loop
ID setting. The default is Disabled.
• Hard Loop ID—When this setting has a Loop ID other than 0, the HBA uses the ID specified
by this setting. The default is 0.
• Spin Up Delay—When this setting is enabled, the BIOS waits up to two minutes to find the
first drive. The default is Disabled.
• Connection Options—Defines the connection type. The default is 2. The options are:
•0–Loop
•1–Point-to-point
• 2–Loop preferred, then point-to-point
• Fibre Channel Tape Support—When this setting is enabled, FCP-2 recovery can occur. The
default is Enabled.
• Data Rate—This setting determines the data rate. The default is 2. The options are:
•0–Runs at 1 Gb/s
•1–Runs at 2 Gb/s
• 2–Auto negotiates and determines the data rate
•3–Runs at 4 Gb/s
Selectable Boot Settings
This option lets you select the node from which you want to the system to boot. When enabled, this
option forces the system to boot from the selected Fibre Channel hard disk, ignoring any IDE hard
disks connected to the system. When disabled, the system looks for a boot device (specified in the
system BIOS). When disabled, the Boot ID and Boot LUN parameters have no effect.
NOTE: This option applies only to hard disks; it does not apply to tape drives and other nondisk
devices.
