. . . very thoughtful of you to give the options as you see them; but an ASUS 2.0 SLIC will work fine for installing Vista - I have an Asus DVD - into this little box. . . hope the eats is good . . .
I have no idea of what that tool is...but you extract the files and let me know when it is done and where I can download it.....
You may have to install the non-modified bios first and then it will probably allow you to back it up with whatever Bios Update Tool that is in the .EXE file....back that up and send it to me.
