Yeah, its works:)

Just to recap for anyone reading this thread after me:dd if=/dev/mem of=vgabios.bin skip=1536 count=128

1.  Get http://atrey.karlin.mff.cuni.cz/~mj/pciutils.shtml
2.  Get the freebios2 source
3.  Build the freebios2/util/vgabios
    A.  You may need to modify makefiles to suit your needs I did
        in order to get it to build under a 64 bit machine.  You want 32 bit apps.
4.  Do dd if=/dev/mem of=vgabios.bin skip=1536 count=128 on the card when it up and running normally
5.  On the target machine, preferably in your initrd
    Put the following line:
    ./testbios -s 65536 -d 0x200 -t --abseg /dev/mem ./vgabios

Thank you for all your help:):):):)

Thanks,
Dave

It means there was NO ERROR. It ran perfectly. If it is the case, you 
should see acrambled screen at this point.

The correct command line would be:

   ./testbios -s 65536 -d 0x200 -t --abseg /dev/mem ../nvbios.bin

BTW, you need recent CVS tree to make it work on s2885.
