Hello
First ask you to excuse me for my bad English.

After changing the original video card which is nvidia 8600M GS 512mb with the following nvidia geforce 9300M GS 256mb get the following problem. After starting my laptop shows the following inscription.
"Reflash MXM ROM or add MXM structure and associated callbacks to SBIOS! Post will be halted to 30 seconds and performance will be limited to balanced performance mode until this is resolved ..."
laptop is asser aspire 5520
After 30 seconds of start up and everything looks normal, but actually the video card works at much lower frequencies than normal for this error. I read here and there through google for my problem but do not speak enough English here and there do not understand some things.
As far as I knew would have to flash to you vBIOS-a.
The first thing I did is to run gpu-z to see what happens. You will get 2 pictures from this program.
Then install nibitor and see there the frequencies and modes in which the card can run as far as I know there are 4, but for now only works on 1 and 2. But when you start encountering the following problem. Tush on the Tools> Read BIOS> Select Device and I write this Cant connect to servece manager!
But when you do save a Bios from GPU-Z and loading it in NiBiTor everything was fine and I can do it and save what can be used for flash.
The question is whether to try to reflashna?
Thanks in advance to all.
