sanboot problems.

I would suggest you follow the http://ipxe.org/howto/winpe to boot a custom-made WinPE made with AIK/ADK instead of booting the Windows 7 install DVD locally. That should hopefully allow you to install to the iscsi volume. You might also need the set gateway 0.0.0.0 trick (before the sanhook command) if your router is not set up properly (routes packets back to local network).
