Prepare your BSP for Magneto:
Choose/Get a sample BSP for Magneto
Make your block device driver ready for Magneto
      New features, new IOCTLs
Modify/Add configuration files
      build environment, SYSGEN_xxx …
      files in Platform/%_TGTPLAT%/files
“Magneto Pre-Release Documentation”
Build IPL for your device:

Build the disk image for your device:
    Set MAKEIMG_BIN_FORMAT=imageupdate
    Set di_debug_info=1, for more error messages

Debug the XIP kernel:
      Persistent storage should be mounted as ROOT(“/”) in Magneto
      Hive-based Registry
      Make sure the drivers and files which are needed to mount IMGFS and persistent storage are all in XIP kernel
      Correct Registry setting
      rgucomp –o boot.hv > boot.hv.txt
Registry setting for IMGFS (1/6):

    "RequireCertMod"=dword:1
    "ProfileDir"="Documents and Settings"
    "SystemHive"="Documents and Settings//default.hv"

; Valid Bits for Flags registry value
; If no flags are set, the hive will be stored in the object store.
;
; 0x00000001    Start storage manager in boot phase 1 for hive-based registry
; 0x00000002    Start device manager in boot phase 1 for hive-based registry
; 0x00000004    Start storage manager in boot phase 1 for registry in
;                         external ROM (such as BINFS)

Suggestions for Debugging:

Verify the contents of your disk image
Check your device drivers
FMD driver, … etc.
Check the media contents in your device
Check the registry settings
rgucomp –o boot.hv > boot.hv.txt
