I got word that nomad is working on it as well. He is also looking at the V26 code to see if he can turn it on with the released version.

Below are the details from Nomad that should be helpful to anyone trying to make an image swap program. Nomad has already proven that this process works in an earlier post. I installed his navboot file in my V26.09 image and it worked perfectly. Although his test version has the HACKED BMW logo, with skull and crossbones.... Not sure my wife would be hip to that splash screen.




System works on MIPS CPU and OS-9000 software by Microware.
Each program, library or data file stored in a structure called 'module'
Each module has a header, body and CRC value.

First thing you need to do is extract all modules from 'navboot' file.
Here is some tips:
WORDs and DWORDs are stored in big endian format (most significant byte
first)

Each module started from 'magic' bytes sequence: 4D AD 00 02 which indicates the start of module header.

DWORD at offset 0x04 is the module full size DWORD at offset 0x0C is offset to module name (ASCIIZ string) DWORD at offset 0x24 is offset to module body

There are a lot of other fields such as module type, access rights, creation date etc.
Last 3 bytes is module CRC.
