Plz help me someone with this:
I want to grab blizzppc.device from memory to a proper file. Or maybe from the BlizzardPPC firmware update file? Is it possible somehow? If so, plz show me the way! Thanks!
You can't. Or at least not easily. The devices normally are PC relative or use a custom relocation scheme to execute itself from the bootrom or after being copied to ram. This means that in 99% of the cases you will not be able to create a relocatable DOS executable from a rom content. Doobrey has spent ages in manually obtaining the relocation information for the Kick 3.1 rom to create custom roms with RomSplit and Remus.
The Deneb stores its files in original DOS Hunks in the flashrom. The bootloader then simulates the LoadSeg operation to do the relocation into fast ram. I wouldn't expect other bootroms doing this rather complex job.
