if the problem is still ongoing (2 weeks since last message), 2 development:
- drivers have fixed the problem on the zotac boards, but as it was chipset related (NV79/NV7A), it seems unlikely to help.
- if you need to dump the bios of your c2070, you could do a USB stick boot with nvflash and get your bios this way:
* create a DOS usb boot
* load nvflash DOS on it ( http://www.techpowerup.com/downloads...126.96.36.199.html
* execute nvflash --save c2070.rom
* zip and attach that rom file here
