• Manage Run-time Images• Protect Disk Volymes (Enw)• Boot and Run an Operating System from a CD-ROM • Boot a Device Over a Network

– The Remote Boot service implements a Pre-boot Execution Environment (PXE), allowing for a network to act as a boot device. This allows you to configure a client remotely without requiring the client to have a storage device. PXE is invoked at startup of the client and communicates with the server to retrieve a boot image across a network.

Embedded Windows XPTo build a bootable CD-ROM run-time image 1. On your development system, in Target Designer, create your configuration. Include the

following components in your configuration: – Winlogon Sample Macro Component – El Torito CD Support This Macro Component contains all of the necessary bootable

CD-ROM support components, including El Torito, Enhanced Write Filter, Background Disk Defragmentation, CDFS and CD-ROM drive components.

– Target hardware device drivers Individual drivers can be added to the target system manually, or you can create a devices component by using the Target Analyzer utility.

2. Run a dependency check and correct any unresolved dependencies. - If prompted to choose between EWF NTLDR or NT Loader, choose EWF NTLDR.

3. In the Enhanced Write Filter component settings, Clear the Start EWF Enabled check box. When First Boot Agent (FBA) runs on the target system, EWF must be disabled. Leave the default values for all other settings. Verify that Disk Number equals 0 and Partition Number equals 1 for the target disk volume. El Torito supports EWF RAM Reg Mode only. EWF Disk and RAM modes are not supported in El Torito configurations.

4. If your configuration includes the Explorer shell, select Show Run on Start Menu in the User Interface Core component so you can run console applications.

5. Build the run-time image. Be sure that the image builds without errors. 6. Transfer the run-time image to your 650 MB FAT boot partition.

Embedded Windows XP1. Review the Bootable CD system requirements. Verify that all the appropriate

components and configurations have been included.Bootable CD-ROM Design Considerations

2. Build the bootable CD run-time image. Include all components required for the bootable CD-ROM and any hardware devices on the target system.Building a Bootable CD-ROM Run-Time Image

3. Create an ISO file of the run-time image using hd2iso. Use the ISO image to create a CD-ROM that is used to identify the CD-ROM device during the FBA phase.Writing a Bootable CD-ROM

4. Boot the run-time image on the hard drive partition and run First Boot Agent (FBA). When Windows XP Embedded starts, verify that EWF is enabled.Running FBA on the Bootable CD-ROM Run-Time Image

5. Run ETPrep and reboot the system. ETPrep deletes the temporary EWF partition and configures the run-time image to boot from the CD-ROM device.Running ETPrep.exe

6. Convert the post-FBA run-time image to an ISO file. This follows the same procedure as in step 4. This CD-ROM contains the final run-time image that can be deployed.Writing a Bootable CD-ROM

7. Burn the ISO file to CD-ROM and deploy.Deploying the Bootable CD-ROM

Embedded Windows XPDeveloping Components

1. Determine the resource requirements of the application.Determining Application Resource Usage

2. Determine how many components to create for the application.Component Boundary Analysis

3. Write descriptive Help for each component.Component Help

4. Create a component definition (.sld) file.Creating an SLD File

5. Create one or more repositories for the components.Creating a Repository

6. (Optional) If the components have more than one repository, create a repository set and add those repositories to the set.Creating a Repository Set

7. To manage related objects more easily, create a package to hold the application components and their repositories.Creating a Package

8. Create one or more components for the application. Creating a Component

9. Import the new components into the component database.Importing an Object into the Database
