Wrong flash on HD2700 in FSC Xi2550

[MrKGB]

Hi

First sorry for my english

I have a problem with an no working flash of a HD2700 mobility radeon.

I got the orginal biosfile with GPU-Z 0.31 and opend it with RBE 1.18.
I changed the clocks for powersaving in all "Fields" displayed to the factory Clocks given in powersaving (110 Core 252 MEM at 0,9V ) with RBE 1.18.
Then flashed the modifiyed BIOS to the HD2700 with Winflash.
Winflash sayed flash succesfull , reboot.
After reboot the Display stays black but the laptop seems to boot.
I had a backup of the orginal BIOS so i tryed to reflash it in a blindrun with atiflash 3.6 (and the parameters -f -nw , also tryed 0,1 for different devices)from a bootable CD.
But i didnt work. in lack of any display massages i tryed to save the log on a HDD drive to se whats the problem.
The problem is that atiflash -i cant find any adapter to reflash.

Can you get into the BIOS setup screen??
Have you tried with an external monitor??

I have no working Display (stays black but Laptop boots etc.)
External Display dont work :-( , So there is no possibility to see the mobo bios! Eventually a blind change of Bios options is possible (have to know the command order from an xi2550 user with display and typing them blind )
I read Winflash bases on Atiflash , when this is right why the flash with winflash worked while atiflash can`t find the HD 2700???
Do you think the problem is the Mobobios or an Option on it (wich on you think?)

If it might help some expert programmer/tweaker i can send you the orginal Biosfile saved with GPU-Z.
