Win 7 Install CD/DVD Device driver needed?

I had the same issue: couldn't install Windows 7 RC because of that request for a CD/DVD device driver.

I had burned the iso image with the free version of Ashampoo Burning Studio 6.

This laptop, a Thinkpad Z60t, had run Windows 7 beta just fine.

I downloaded another copy of Windows 7 and burned a second image with Ashampoo. That gave me more messages, including not enough disk space.

Finally, I downloaded a third copy of 7 and burned it with ImgBurn. This copy installed without a hitch. Using Windows update, I got all the required drivers except two - the Sierra wireless card (which I don't use anyway) and some "unknown device." I'll keep trying to figure out what the unknown device is and may try to find the Sierra drivers just so I don't see yellow question marks in device manager.

Bottom line: I have to wonder about the quality of the image burns on the first two downloads.

Found the Sierra wireless driver and installed driver for "unknown device." It turned out to be Atmel TPM (Trusted Platform Module). Glad to dispose of those yellow question marks.

Dek, my appologies, the Chassis Intrusion alert is a jumper related feature

If none of the pins are jumped then the feature is enabled - and any mod to the board sets off the intrusion feature - if you jump the pins indicated in the image below you should solve the problem:
