The LSI Logic SCSI BIOS Conﬁguration Utility Menus 3-9

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.

Caution: Neither of these options has any effect after

a disk has been partitioned using the FDISK

command. The FDISK utility is a tool that the user can

use to delete partition entries, one or all of them. If

all partition entries are deleted, it is necessary to

reboot to clear memory or the old partitioning data

will be reused, thus nullifying the previous operation.

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 LSI Logic 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 automatically

determines whether it should enable or disable its

termination. Auto is the default state unless

termination is done manually, in which case, the

conﬁguration is Off.

<Restore Defaults> Executable Press Enter to obtain default settings.
