testbios loops?

Hi,
 
  I went back to trying to get the Nvida 6800gt card's bios, but still
even with dd -if=/dev/mem of=vgabios.rom skip=786432 bs=1 count=32768
I get the same binary as dd -if=/dev/mem of=vgabios.rom skip=1536
count=64.
I used dhex (free util) to verify they are the same.
  What happens when I run them trough testbios is that once it is done
programming
0xc7fff it jump to 0x9 something or other and the video bios isn't
programmed correctly.
My iomem looks like this:
 

00000000-0009fbff : System RAM
0009fc00-0009ffff : reserved
000a0000-000bffff : Video RAM area
000c0000-000c7fff : Video ROM
000f0000-000fffff : System ROM
00100000-1ffeffff : System RAM
  00100000-002b00be : Kernel code
  002b00bf-003d78bf : Kernel data
1fff0000-1fffefff : ACPI Tables
1ffff000-1fffffff : ACPI Non-volatile Storage
c9f00000-c9ffffff : PCI Bus #01
ca000000-ca0fffff : PCI Bus #02
ca100000-ca1fffff : PCI Bus #03


  Any ideas as to what is wrong?

 

Thanks,

Dave:)
