I have found the only in/common aspects to other bioses being 1 quad locked DIE, and 2 quad locked via rom, and GB_PIPE_SELECT being equal to my card, both of these cards came from sapphire, only one is x800GT that unlocked to x800pro 12pipes. Perhaps my card came from the same lot as that GT, same GB_PIPE_SELECT addresses? I have not found any PRO-vivo bioses with CONFIG_FUSE_ROM or GB_PIPE_SELECT that match to mine.
I went through hundreds of pages and found 5 cards listed by posters that all had something in-common, That being the card was either x800 series having the ability to use up to 12 pipes "meaning either OPEN CORE or DIE LOCKED 1 quad and have found 5 unique card configurations with different GB_PIPE_SELECT settings.
as follows
UNIQUE config number 1
open die fueses x800gto 1/2, 12 pipes enabled,
ROM_FUSE=0x261 or 0x861 "pci-e?"
GBPS=0x2724
UNIQUE config number 2
DIE LOCKED 12 pipes enabled x800pro sapphire AND power color x850pro R480
ROM_FUSES=0x20 for sapphire
ROM_FUSES=0x261 for Power Color x850pro R480
GBPS=0x227A4
Unique Config number 3
DIE LOCKED to 12 pipes "UNDER THE CORE" PCI-E PRO-VIVO
GBPS=0x6E48
Unique Config number 4
All either OPEN OR Die locked to 12 or 8 pipes, all are x800GT/0 agp or pci-e
in the case of the Die Locked to 12 pipe card being ROM locked to 8 pipes x800GT, the ROM_FUSES=0x862 and GB_PIPE_SELECT=0x12B84 This is interesting!
in the case of the non vivo, non pro x800 sapphire hybrid it was DIE locked "SUBSTRATE AND DIE had ODD FUSE CONFIGURATIONS but I DIDN'T make a note; it was not ROM locked
ROM_FUSES=0xA60
GBPS=0x12B84
I am not sure how to change the ROM_FUSES from the characthor 6
108 to match 4021 and haven't found GB_P_S within the hex I havn't found another bios available for download that has ATI TOOL results showing GB_P_S=0x12B84
