11、tion of custom components target analyzer (ta) creates definition of target hardware td: component selection selection of macro or component browse by category search and filtering pre-selection estimation of footprint impact component help td: configuration os & components are configured for target

12、 device os configuration: hardware support file system machine name pagefile destination drive etc. component configuration varies by component configurable through dhtml equivalent to os setup time configuration td: check dependencies check dependencies identifies and adds required components based

13、 on dependencies task 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 configuration generates file system folder containi

14、ng os files copy to bootable partition boot first boot agent runs for online configuration component designer creation and editing of components for use on embedded devices developer specifies name, version, author, etc. files & registry data (from local pc) group or file dependency (from component

15、db) component category membership build order dependencies required system resources component saved as .sld file files & metadata are imported into repository & database target analyzer target analyzer simplifies configuring os image for target hardware application that runs on target device genera

16、tes xml definition of target hardware (.pmq file) hardware definition: imported into component designer creates component with dependencies on the identified hardware drivers imported into target designer, adds appropriate device drivers to configuration runs under xp, winpe, dos component designer

17、& target analyzer embedded enabling technologies sdi os image format and supporting tools image cloning & reseal mass deployment of near identical images remote boot allows booting from server via pxe device update agent light-weight servicing client winpe bootable “xp” installation platform enhance

18、d write filter protect os partition in embedded devices cd-boot “el torito” implementation uses read-only media for system sdi sdi is a portable file format for xpe images virtual disk drive disk image backed by .sdi file partitioned, formatted, bootable tools for building, editing and extracting im

19、ages sdi loader gui tool creating, mounting, dismounting sdi files as drives sdi manager command-line tool for manipulating sdi files off-line sdi uses managing large numbers of bootable images target designer builds into mounted drives image format for remote boot ntldr has support for sdi images r

20、emote boot manager allows configuration of sdi image to mac address sdi file format partition blob loader blob boot blob header sdi signature boot offset & length extensible (4k) boot program startrom.com real mode executable file call ntldr.exe loader program ntldr.exe mounts partition blob as ramd

21、isk boots into ramdisk target runtime image post fba xpe image disk blob image cloning & reseal mass deployment on nearly identical hardware run-time image must be adjusted for serial no, mac address, sid, etc. include the system cloning component two phases: reseal and cloning allows fba configurat

22、ion allows manual installation of applications post build use sdi to deploy resealed image remote boot overview boot an embedded device over a network targeted at pos scenarios intended for diskless devices requirements windows xp embedded run-time image device has bios pxe support, tcp/ip network w
