I built a computer for myself and my frient with the cusl2 and a 700 running at 933 to 1000. For flashing the bios on the cusl2, I found that if you set the bios to use the onboard video before flashing, everything works fine. So, turn the onboard vga on and change the order from agp->pci to pci->agp. When I did this I didn't have any problems. When I flashed the second computer and didn't do this.... well, you have all seen how well it works. Playing with that battery or shorting the connection is not fun, but this seems to work, I haven't tried it flashing to the new bios, but I will and I will post how it works.
