pull the 6870 out
and clean the cmos it won't boot with the other card untill do you do this!!!
boot the machine with either the onboard video or the pci card
go into the bios and set the display priority to either the PCI card or the onboard video ALSO REQUIRED it will not work unless you change the display adapter priority to something else(look for a setting labeled video device priority or display boot device or something similar )
reboot and shutdown
re-install the 6870 leave the video cable connected to the on board chip/pci card
boot from a usb key cdrom or something that has a dos prompt and a RECENT copy of atiflash
run atiflash -i find the 6870's number
then to flash run
atiflash # -p biosfilename.bin
reboot clear the cmos again and remove the pci card/switch the cable over to the 6870 and pray
#=the number of the gpu listed when you did atiflash -i
