remember my Image is located at first of my 256K flash part
and is 32K big, are these values correct.

0xfffc0000 i don't know
0xc0000 should be correct
0x8000 yes

Mmmh, the pci_rom_run detected the right signatur on 0xfffc0000
also this should be correct to.

Waaah. Ok, how can I verify, that the vga.bios image is proper copied to 
0xc0000. I think the emulator reads from this adress, right?

Now, where the emu is stopping with halt_sys. I'm able to read out 
0xc0000 with dd and voila, there is definitivly not the vga.bios.

$ dd if=/dev/mem of=vga.bios bs=1 count=32768 skip=786432

I get garbage :D
