Need Bootloader Help

I killed my Simpad after flashing WinCE 4.0 via internet.

As a result, there was no active bootloader.
(cyclic message "PBL V2.4 20.07.2001, Booting,..." in terminal)

In the forum I read about a tip of Walter Schweizer, to connect the pins
1+2 of the test field, to activate the internal piggyback bootloader. It
worked.

Unfortunately this loader can't load a WinCE-Image. I think because of
an overlapping address space:

    Base   : 0x1080014 Size 27371523 entry:0x4081000
    Overlap: 1080014-2a9a817   && 1f00014-1f74b9c
    Will fail -- try to load alternate loader: loader.alt

Downloading the 2.5.3 bootloader was successful!
But it seems, that the old loader (address 0x01f00014) gets activated
again after a reset:

    Load finished with 10kB/sec
    Starting Image at 8014 PPCR 0x0000000a

    PBL V2.4 20.07.2001
    Booting...
    ================================================
    Siemens Switzerland Bootloader V2.4 20.07.2001
    Running @206Mhz Processor ID 0x6901b118
    Press ESC for monitor
    Occupied Memory: [0x00004000-0x00008000],[0x01f00014-0x01f74b9c]
    Flash Id 0x00000018 at virt adr 0x05000000 Size 0x01000000

Because I don't want to integrate the JTAG interface yet: 

Can anybody give me a hint to manipulate the startup address after a
reset, so that the new bootloader runs instead of the piggyback one?

Please help,...

Michael
