I had someone point out this little tip to me. If you starting a machine from scratch and you need to find the model of the video card, you can use Debug to view the video bios to get the information you need. Simply run the following command from within Debug:
The manufacturer may not be evident on the first group that comes up. In that case, keep typing d and hit enter, eventually you will scroll down to the find manufacturer. Useful trick if you are on a Microsoft platform and you need to search for drivers. However, in the past I usually just throw in a bootable Linux Live-CD and view the /proc files to find the video card manufacturer, however that does not always work (although I have pretty good success using Knoppix).
