Help adding a single file (INITOBJ.TXT) to an OS ROM image

[geckman]

Forgive my naiveity in this area, (and I'm sure what I'm asking here is obvious to most), but I'm trying to replace the INITOBJ.DAT file in an OS ROM image and need some help.

I'm using: ROM ver 3.20.06 ENG and Bootloader 6.22

I have backed up the OS image using OSImageTool, as ROM.NB1
and edited the INITOBJ.TXT file in readyiness for my new ROM.

1. Can I use MKROM without a bootloader image and get it to create my
new OS ROM image ?

2. Can I use any of the other tools to add the INITOBJ.DAT to my OS ROM
image ?
If so can you show me the steps ?

Thanks
