BIOS reading not supported

[Arise]

And yes, my BIOS also gives me:
GPU-Z speaks: "bios reading not supported".

Also, I get same sort of message when I use Ati Tray Tools t dump the bios.

Also, using AtiFlash, I've got the folowing info:

atiflash -i
adapter bn dn dID       asic           flash      romsize test    bios p/n    
======= == == ==== =============== ============== ======= ==== ===============
   0    01 00 7149 RV5x5/M54       No ROM            -      -        -

atiflash -ai
Adapter  0    (BN=01, DN=00, PCIID=71491002, SSID=010D1025)
    Asic Family        :  RV5x5/M54      
    Flash Type         :  No ROM      ( 0 KB)
    No VBIOS

Am I out of luck?

When I like to "save a file...",it showed "BIOS reading is not supported on this device"

How can I get that?I need it eagerly.I need to make my video chip work on Hackintosh(OSX86)

Any one can help???
Thank you so much

I have the same problem with ATI mobility FireGL V5000 (mobility x700 (M26)). What can I do to help developers to add support for reading bios on this video card?
