Force Boot Option Use this option to determine how the BIOS handles a configuration
mismatch. A configuration mismatch occurs when the configuration data on
the NVRAM and that on the hard drives are different.
If you set the Force Boot Option to On , then when a configuration mismatch
occurs, the BIOS reads the configuration data that exists on the hard drive,
writes it on NVRAM, and reboots the system. The options are
On and Off .
The default is On .
Bios Stops on Error When set to On , the BIOS stops in case of a problem with the configuration.
This gives you the option to enter the configuration utility to resolve the
problem. The default is
On .
BIOS Echoes Messages When set to On (the default), all controller BIOS messages display during
bootup.
Bios Config AutoSelection Use this option if there is a mismatch between configuration data in the
drives and NVRAM, so you can select a method to resolve it. The options
are
NVRAM , Disk , and User . The default is User .
Spinup Parameters Use this option to set the timing for spinning up the hard disk drives in the
computer. The options are
Automatic , 2 per 6 sec , 4 per 6 sec ,
or 6 per 6 sec . The default is 2 per 6 sec .
Fast Initialization When enabled, zeros are written to the first sector of the logical drive so
that initialization occurs in 2 to 3 seconds. The options are
Enabled and
Disabled . The default is Enabled .
When disabled, a full initialization takes place on the entire logical drive. On
a larger logical drive, LSI recommends disabling fast initialization, then
initializing. Otherwise, the controller runs a background consistency check
within 5 minutes of reboot or RAID 5 creation.
PCI Delay Trans Use this option to enable PCI delay transfers, which improve performance
on some older system boards. The choices are
Enabled and Disabled .
The default is Enabled .
Auto Rebuild Use this option to automatically rebuild drives when they fail. The options
are
Enabled and Disabled . The default is Enabled .
Class Emulation Mode Use this option to select I
2
O or Mass Storage as the class emulation
mode. The default is Mass Storage . This option allows the firmware to
use I
2
O drivers or regular drivers.
Temporary RAID Offline Use this option to allow the firmware to bring all the drives in an array back
online, except for the first failed drive. The default is
Disabled . Enabling
this option gives you access to the array. If disabled, you cannot access the
array if there are two or more failed drives in the array.
