Strange Option menu during Install of x64

[Saltgrass]

During my install of Windows 7 (and Vista) x64, I was presented with an options screen which seems a little strange. The text on the screen is presented below, does anyone know what it up? I do use a SATA DVD drive, but no other CD/DVD drive installed.

1.
2.
Select CD-ROM Boot Type:

I have always selected 1, but I don't know what that means. I am assuming it is associated with the x64 install, since I do not get it on the x86 installs.

Strange indeed.

Where did you get your copy of W7? Is it the official BETA ISO from microsoft?

If not, it could have been tweaked by someone to include other boot options.

Never seen those options on my installs using x64, I would say it's something in your bios that is prompting these options, try restoring optimized defaults and see if you still get it.

Copy downloaded from Microsoft, so no tweaking going on.

It could be something in the Bios, but this motherboard (Intel DX48BT2) auto configures everything. I will look at the boot options to see if anything sticks out, but I can't even think of what type of options it might be requesting. I would tend to believe it must be the 64 bit install that is triggering the prompt. Also seems the prompt shows up during the initial boot/install and the first reboot, and then does not come back, if I remember correctly.

Mr. Grim, are you using a SATA DVD drive for the install? This really isn't a problem for me now, but I thought I needed to bring it up. Of course, I have no way of knowing if it effected the install.

Yes I am using SATA everything and I actually have IDE disabled in my BIOS, actually I have heaps of stuff disabled in the bios.
