prototypingDesign Templates:starting point for device developmentSet Top Box,Home Gateway,Information Appliance,Kiosk,Network Attached Storage,Point of Sale,Windows Based TerminalHelper MacrosA generic set of components that allows the user to quickly build a run-time image without identifying specific hardware.Eliminates tasks by configuring commonly-used settingsTechnology MacrosAggregation of functionally related componentsDirectX,IE,etc.,XPe Component Database,Components and Macros metadata stored in SQL DatabaseLocal database in MSDEShared database in SQL ServerComponent repository(OS binaries)in file systemNew database ships with SP1Unmodified RTM components&updated SP1 componentsAll QFEsMUI Languages:8 in box,14 on web at launchExisting configuration will work unchangedUpgrade paths from RTM components to SP1 components,Developer Tools,Target Designer(TD)Composition and configuration of components into bootable OS imagesComponent Designer(CD)Creation of custom componentsTarget Analyzer(TA)Creates definition of target hardware,TD:Component Selection,Selection of macro or componentBrowse by categorySearch and filteringPre-selection estimation of footprint impactComponent help,TD:Configuration,OS&Components are configured for target deviceOS Configuration:Hardware supportFile systemMachine namePagefileDestination driveEtc.Component ConfigurationVaries by componentConfigurable through DHTMLEquivalent to OS setup time configuration,TD:Check Dependencies,Check dependenciesIdentifies and adds required components based on dependenciesTask list prompts user for component selection based on category,TD:Build Target Image,Builds a bootable OS Registry hives,folders and populating binaries to folders Based on resource information and settings of components in the configurationGenerates file system folder containing OS filesCopy to bootable partitionBootFirst Boot Agent runs for online configuration,Component Designer,Creation and editing of components for use on embedded devicesDeveloper specifiesName,version,author,etc.Files&Registry data(from local PC)Group or File

Analyzer,Target Analyzer simplifies configuring OS image for target hardwareApplication that runs on target deviceGenerates XML definition of target hardware(.pmq file)Hardware definition:Imported into Component Designer creates component with dependencies on the identified hardware driversImported into Target Designer,adds appropriate device drivers to configurationRuns under

mac addressExtensible based on published SDI image format supported by NTLoader,Remote Boot Architecture,Clients,DHCP Server,Redirection ServiceBoot ServiceTFTP Service,Device Update Agent,Lightweight management solution for small footprint devicesMinimal dependenciesFlexible command set to address a broad range of scenarios,Key DUA Scenarios,Update applications or application data Apply QFEs or system updatesDeploy new components or device driversAutomate cleanup and management tasks,DUA Features,Execute local or remote command files(Push vs.Pull)Flexible scheduling with jitter and polling optionsConfigurable within Target DesignerBroad command set,DUA Command File Execution,Command files are executed immediately upon acquisitionCommands are processed sequentiallyFailure modes are specified by each commandErrors are logged to the event log,DUA Security Considerations,HTTPS with auth is offered as a secure transfer optionCommand files are not in plain textPoll locations should be securedIncorporate additional security mechanisms if necessary(i.e.VPN,encryption,IP filtering),DUA Architecture,Device Update Script(.DUS file),Translator,Validate and Tokenize,Command File(.DUP),XPE Device,Device Update Agent,HTTP/HTTPS,Update Web Server,Local File Storage,Development Environment,DUA Best Practices,Test and deploy on known configurationsPlan for updates scheduling,distributing load,http requirements Command files should update poll locations on completionServers should not issue redirects,WinPE,WinPE is Windows XP Pre-install EnvironmentLightweight

Components,EWF ComponentA component you add to your run-time image add EWF support to your image.Includes settings to configure EWF on your deviceEWF NT Loader(EWF NTLDR)Required if booting from an EWF protected media that is writeable(i.e.,hard disk).Not required when used with CD BootEWF Manager ConsoleA component you can add to your configuration that allows reconfiguration of EWF on the embedded device.,Configuring EWF,At design-timeUse the settings pane in Target DesignerAt Run-TimeAdd the EWF Manager Console component to your image.,CD-Boot,Allow XP Embedded to boot from a CDXPe implementation of El ToritoOnly one bootable partition allowed Bootable partition must be the first partitionEnhanced Write Filter(non-persistent)to store information during the sessionAllows use of read-only media for systemUse CD-ROM for system Redirect disk writes to memory or other storage medium Persistent EWF is not supported with CD-Boot,OS Footprint:Sample Configs,Applications,XPe
