Note Default values are bolded.
 
Field Description Possible Values
Battery Backup Battery Backup module presence is detected at the time of POST and the results are displayed here. None
Present

Note: This field isn't user configurable.
RAM Size Cache RAM memory is detected at the time of POST, and the results are displayed here. 64M to 1G

Note: This field isn't user configurable.
Cluster Mode This field should be set to Enabled if the adapter is used in a cluster. Disabled
Enabled
Initiator ID This field should be set to the desired SCSI ID if this adapter is not the primary adapter used in a cluster. 1 to 30
7
Rebuild Rate This field allows you to determine the priority for the rebuild operation. This option selects the amount of system resources devoted to rebuilding failed disk drives. A higher percentage rate rebuilds drives faster, but can degrade the system performance. 0 to 100
30

Note: Setting the rebuild rate to 0 will prevent the array from rebuilding.
Flex RAID PowerFail Allows drive reconstruction to continue when the system restarts after a power failure. This feature uses 2 MB of logical drive space for rebuild and reconstruction process tracking. Disabled
Enabled
Alarm Control This field allows you to determine how the audible alarm behaves. The possible values here are Disabled, where the controller will not enter alarm state, Enabled, where the controller will enter alarm state and audibly alarm, and Silence, where the controller will enter alarm state but not audibly alarm. Disabled
Enabled
Silence
Adapter BIOS This field allows you to set whether or not the Option ROM is loaded at the time of BIOS POST. If disabled, the adapter BIOS control-G screen is not seen during POST. This field must be enabled if the attached array is the boot volume. Disabled
Enabled
Set Factory Defaults This field allows you to return the adapter properties back to their original factory settings. The array configuration remains unchanged. No
Yes
Coercion Algorithm Drive coercion refers to the ability of the controller to recognize the size of the physical drives that are connected and then force the larger drives to use only the amount of space available on the smallest drive. Drive coercion as implemented in these Intel® RAID Controllers also allows an option to map out a reserved space to compensate for slightly smaller drive sizes that may be added later. This option allows 16 MB, 256 MB, and 1 GB of drive capacity to remain unused. None
128MB-way
1G-way
BIOS Stops on Error This field allows you to determine the behavior of the installed system upon encountering an BIOS POST RAID error. The possible values are On, where the system halts POST when RAID errors are encountered, and Off, where BIOS POST continues past any RAID errors. Off
On
BIOS Echoes Messages This field allows you to determine the visibility of RAID error messages. The possible values are On, where error message are displayed in the BIOS POST, and Off, where error messages are only displayed in the user interface. Off
On
BIOS ConfigAutoSelection This field allows you to resolve mismatched RAID configurations by determining from where the RAID configuration is drawn. Possible values are User, where the RAID configuration is drawn from what has been configured during the current user interface session, NVRAM, where the RAID configuration is drawn from adapter memory, and Disk, where RAID configuration is drawn from the on disk configuration. Disk
NVRAM
User
Spinup Parameters This field allows you to determine how many hard drives spin up at a time. Setting this field to other than automatic will slow POST times, but may be necessary on systems with large numbers of drives where those drives are seen intermittently. Automatic
2 per 6 sec
4 per 6 sec
Fast initialization Initializes the logical drive by writing zeros to the first sector of the logical drive. The fast initialization completes in 3 seconds. Standard initialization writes zeros to the entire logical drive and take longer. Disabled
Enabled
PCI Delay Trans This field allows you to control this PCI 2.1 standard feature. The possible values are Disabled, where the controller cannot release the PCI bus until the transaction is complete, and Enabled, where the PCI bus can be released for other devices while the controller operation is being completed. Disabled
Enabled
Auto rebuild Enables the firmware to start a rebuild operation when a failed physical drive is replaced by another drive in the same slot. This feature is different than the hot spare capability. A hot spare drive is automatically used by the system to rebuild an array, without any operator intervention. On the contrary, Auto rebuild enables rebuilding the array only after the failed drive has been replaced. Disabled
Enabled
Class Emulation Mode Adapter BIOS type is detected at POST and displayed here. Mass Storage

Note: This field isn't user configurable.
 
Note Most controller (referred to as adapter in the software consoles) options can only be set by using the Intel® RAID BIOS Console. The only option that can be set using the Intel® RAID Web Console is Rebuild Rate.
