Xfx nforce 680i LT drivers for windows 7

OK,

first time here. Hope I get this right. I recently got a replacement Video Card for NVidia as my older one has a double lifetime guarantee. I was sent a Radeon 5570 HD card as replacement. However, since I had also replaced Vista to Windows 7, I get no boot up when my comp is 'cold'. I have to wait like 30 seconds then hit the 'reset' button to force the OS to boot up. Once it boots up, everything runs like a dream. No problems/issues at all.
So, I ran a PCI Boot Up card for errors to see what the deal was. I received an error code: 4C Upon searching the manual it came with, Error Code: 4C is... Shadow Video Bios Rom

I have no clue what/where or how to 'enable' this feature. I looked on-line and it seems that older MoBo's need this feature enabled to boot up correctly. Newer boards do not.

So, all in all, I need the [Windows 7] Drivers for XFX NForce 680i LT MoBo {Phoenix Technologies, Ltc}
How to for: Radeon 5570 HD Video card [removal of] Code 4C {Video Bios ROM}[enable]
Used: Starteck Pci Card to get this error code.

Any and all help will be greatly appreciated.

Thank you in advance
