CHS mapping
Configuration
[SCSI Plug and Play
Mapping / Alternate
CHS Mapping]
Defines how the Cylinder Head Sector (CHS) values
are mapped onto a disk without pre-existing partition
information.
SCSI Plug and Play Mapping automatically
determines the most efficient and compatible
mapping.
Alternate CHS Mapping utilizes an alternate, possibly
less efficient mapping that may be required if a device
is moved between adapters from different vendors.
Note:
Neither of these options has any effect after a
disk has been partitioned using the
FDISK
command.
T
o change the CHS Mapping on a partitioned disk,
use
FDISK
to delete all partitions. Then reboot the
system to clear memory or the old partitioning data
will be reused, thus nullifying the previous operation.
Caution:
Use care to ensure that the correct disk is
the target of an
FDISK
command.
Spinup Delay
(Seconds)
Configuration
[1 to 15]
Indicates the delay in seconds between spinups of
devices attached to an adapter. Staggered spinups
balance the total electrical current load on the system
during boot. The default value is 2 seconds.
Secondary Cluster
Server
Configuration
[Yes / No]
Indicates whether an adapter has one or more
devices attached that are shared with one or more
other adapters and therefore, the Symbios SCSI
BIOS should avoid SCSI bus resets as much as
possible.
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 Control
Configuration
[Auto / Off]
If available, the field indicates whether an adapter has
automatic termination control.
Auto means that the adapter termination is on. Auto
is the default state unless termination is done
manually, in which case, the configuration is Off. Off
means that termination for that channel is off.
<Restore Defaults>
Executable
Press Enter to obtain default settings.
