Problems installing OS

While installing Vista Ultimate 64bit on my new Rampage Formula I got the following information on the screen when it tried to reboot;

free DOS Kernel version 1.1.35w(build 2035w-unstable, nov 30 2005)

Kernel compatibility 7.10 WACOMC fat32 support

Somewhere I read something about this being a problem with SATA Optical drives. Does anyone have any information on this? You can see my hardware setup in my sig.

I had only 2GB of RAM installed and I had setup the BIOS for this RAM by setting the freq. to 1066MHz and timings to 5-5-5-15-8 2T and raised the DRAM voltage to 2.20v which are the factory spec's and I set the NB to 1.31v. So I don't think it is the RAM. I have another computer I was putting together at the same time that did the same thing. I was trying to load XP Pro on it and got the same message. The two things these computers have in common are the SATA Optical drives, which by the way are different brands, and they both have ASUS motherboards.

I am at a loss and have sent ASUS a tech request. I think in the mean time I will try to load the OS using IDE Optical drives and see what happens.

Thx's Mondoman for your input and I will return when I have news to report.
