I setup an AMD system with 5.0 using a USB drive and everything worked out fine. I had no issues editing the vender file. I have now switched focus to getting an Intel SS4200 NAS converted over. I am booting from a compact flash card (IDE adapter) and the installation went quite well. I am having issues changing the MAC address. I think it is lack of *Nix knowledge. When I WinSCP over to the box, instead of getting a mount point for the USB stick, I just have \root and a SYN_DATA fodler. Presumably, I need to create a mount point for the CF card. I will muscle through this, but I thought I'd share since others who "cant find the vender file" may be suffering the same problem.
