•The GetNetworkISOImageConnectionInfo() method provides the ISO
Image connection information in the form of several output parameters
that include network share information (excluding password), ISO
connection, and attached status.
•The SkipISOImageBoot() method does not allow the host system to boot
to the ISO Image after a system reboot. After one reboot host continues to
boot to the ISO Image.

• The drivers unpacked and attached are removed after the time
specified in
ExposeDuration parameter. If no time is specified in
the method invocation, then by default the OEMDRV USB device
will be removed after 18 hours.
• Ensure that network based ISO images attached during the process are
detached before you use UEFI System Service.
• The following methods are used to directly detach the local OEMDRV
device or the network ISO image. Use these methods before the previously
set exposure durations time out:
–The DetachDrivers() method on the DCIM_OSDeploymentService
class detaches and removes the
OEMDRV device that had been
previously attached by an invocation of the
UnpackAndAttach()
method.
–The DetachISOImage() method on the
DCIM_OSDeploymentService class detaches and removes the
network share based ISO image that had been previously attached by
an invocation of the
BootToNetworkISO() method.
–The DisconnectNetworkISOImage() method detaches the virtual
USB CD-ROM device from the host server that was attached during
ConnectNetworkISOImage() method.
• Several methods described in this document return job identifiers as
output parameters. The jobs provide a means of keeping track of a
requested action that cannot be performed immediately and, because of
underlying technology constraints, will take longer than standard web
service request response timeouts. The returned job identifier can
subsequently be used in WS-MAN Enumerate or Get requests to retrieve
job object instances. Job object instances contain a job status property that
