1.
The person controlling the direct-network installation starts the process by
booting the target computer with ImageUltra Builder Distribution Media, and then
selects the required maps from the repository.
2.
A network-staging folder is created specifically for the target computer. The
selected maps and a limited number of modules (only those required to control
the installation process) are copied to the network-staging folder, which acts as
a staging area for the installation process.
3.
The person controlling the direct-network installation makes selections from the
installation menus to define the image to be installed.
4.
The modules required for the defined image are obtained directly from the
repository and copied over the network to target computer C partition. Then,
the setup process begins.
Note:
Optionally, if a developer of the image specified that a service partition
is to be created for client-side recovery purposes, the maps and modules
also are copied to a service partition.
When setup is complete, the C partition contains the new image.
ImageUltra Builder relationships with the Hidden Protected Area (HPA)
This section provides information about the purpose of the Hidden Protected Area
(HPA) and the relationships that exist between the HPA and the ImageUltra
Builder program. Additional information about the HPA is available from the
Lenovo Web site at:
What is a Hidden Protected Area?
Implemented in 2003 on selected models of ThinkPad and ThinkCentre computers,
the Hidden Protected Area (HPA) is a variant in the Lenovo disk-to-disk recovery
scheme. Like the service partition, the HPA provides its own operating
environment and contains operating-system modules, application modules,
device-driver modules, and a set of recovery tools. But, the similarities stop there.
The architecture of the HPA provides a secure environment. Protection settings
(security levels) and access to the HPA are controlled by the computer basic
input/output system (BIOS). The HPA does not rely on a boot manager, and is
therefore immune from boot-sector viruses, which could cripple other disk-to-disk
recovery methods.
Each application within the HPA is contained on its own protected service area
(PSA). There are two types of PSAs: Boot PSAs and Data PSAs. Boot PSAs contain
all of the files necessary for starting the application from the associated Data PSA
and for displaying an icon in a secure launching area called the Predesktop Area.
