Frequently asked questions
How to find the boot order (sequence) of the boot
configuration using
DCIM_OrderedComponent.AssignedSequence property?
When a DCIM_BootConfigSetting instance (Legacy or UEFI) has multiple DCIM_BootSourceSetting
instances (boot devices) associated with it through instances of the DCIM_OrderedComponent
association, the value of the DCIM_OrderedComponent.AssignedSequence property is used to
determine the sequence in which the associated DCIM_BootSourceSetting instances (boot devices) are
used during the boot process. A DCIM_BootSourceSetting, whose associated
CIM_OrderedComponent.AssignedSequence property is equal to 0 is ignored and not considered part
of the boot order.
How to change the boot order?
The boot order can be changed using the DCIM_BootConfigSetting.ChangeBootOrder() method. The
ChangeBootOrder() method sets the order in which the instances of DCIM_BootSourceSetting are
associated with a DCIM_BootConfigSetting instance. The method has one input parameter; Source. The
Source parameter, is an ordered array of PartComponent property from DCIM_OrderedComponent
class that represents the association between DCIM_BootSourceSetting instances (boot devices) and
DCIM_BootConfigSetting instance (boot list type-Legacy or UEFI).
How to disable boot devices?
On changing the boot order, the value of the AssignedSequence property on each instance of
DCIM_OrderedComponent, that associates the target DCIM_BootConfigSetting instance with a
DCIM_BootSourceSetting instance that is not present in the input array of Source parameter, is set to 0,
which indicates that the device is disabled.
Fail login message appear when connect to namespace
with wbemtest. How can I overcome that?
Launch wbemtest with Administrator privilege level to overcome any login message. Go to the Internet
Explorer from the All Programs list, right-click and Run as administrator to start the wbemtest and avoid
any namespace oriented error.
