CHS Mapping – This option defines the cylinder head sector (CHS) values that will be mapped onto a disk without pre-existing partitioning information. SCSI Plug and Play Mapping is the default value.

To support interchange with non-compatible systems, there is another option that can be selected by choosing CHS Mapping and then moving the cursor to Alternate CHS Mapping.

Note: Neither of these options will have any affect after the disk has been partitioned with the FDISK command.

To remove partitioning, two options are available:

•Reformat the disk using the Format Device option. See Section 3.2.3, “Device Selections Menu,”below.

•Use the FDISK/MBR command at the C:\ prompt, where MBR represents master boot record.

Important: Reformatting the disk or using FDISK/MBR erases all partitioning and data that exists. Be careful when using either the Format utility or the FDISK/MBR command that you target the correct disk.

After clearing the partitions and data, it is necessary to reboot and clear memory or the old partitioning data will be reused.

Spinup Delay (seconds) – This option allows the user to stagger spinups for a longer period of time to balance the total current load. The default value is 2 seconds, with choices between 1 and 10 seconds.

This is a power management feature designed to accommodate disk devices that may have heavy current load during power up. If multiple drives are being powered up simultaneously and drawing heavy current loads, then this option staggers the spinups to limit startup current.

Secondary Cluster Server – This option allows the user to enable an adapter to join a cluster of adapters without doing any SCSI bus resets. This is a requirement for Microsoft Cluster Server. The default value is No with an alternate option of Yes.

Termination – This option allows the user to have termination control providing an adapter has controllable termination. The default value is Autotermination. The alternate value is Off.
