Dieser Text bezieht sich auf das "alte" dumprom von Anfang 2003, das
noch kein CE 4-Format kannte und generell weniger konnte....
Die Header-Bastelei ist mit der aktuellen Version vom 1.7.2003 nicht mehr nötig. Die
kann zwar mit dem Siemens-Bootblock immer noch nichts anfangen, aber zumindest das Auspacken
der Dateien funktioniert einwandfrei...
Für das/den XDA ist ja schon einiges an "Forschung" getrieben worden, um es
besser zum Funktionieren zu bringen....
unter http://www.xs4all.nl/~itsme/projects/xda/ findet man einiges, wie
das ROM aufgebaut ist, was CE intern so treibt etc., darunter auch dumpROM
(unter "how the windows ce rom is laid out") Näheres auch unter
http://xda-developers.com/.
Leider mag dumpROM anscheinend keine SIMpad-Images - oder doch?
----------Don't wrap this file! We need at least 73 chars/line----------
Ein "normales" CE-Image (In diesem Falle, von einem MoreIO pad...), das mit
dumprom lesbar ist, fängt so an:

Wichtig ist hier der erste "ECEC"-Header, alles davor kann von
Hersteller zu Hersteller (oder von Installer zu Installer) variieren...
als zweites Beispiel ein XDA-ROM:

--------------------------------------------------
Ersetzt man nun den Header des SIMpad-Images durch einen "üblichen"
nbf-Header, kann dumpROM dieses File schon mal auslesen....:
Am einfachsten passiert das mit einem Hexeditor, z.B. mit dem von
Andrew W. Phillips, indem man den Vorspann löscht und das File bis zum
ECEC passend umbaut:

ok, dann mal ein erster Versuch: dumprom test.bin >ce3-020.txt
img 00000000 : hdr=819268b0 base=80080000 commandlineoffset=80080000
unable to determine loading offset for test.bin
nu ja, das ging vorher auch schon, aber jetzt geht das Auspacken:
dumprom test.bin 0x80080000 -d files >ce3-020-files.txt

usw...
So, weil mich eigentlich nur der MS Reader für das SIMpad interessierte,
geht's hier gleich weiter
