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
