Thanks for the reply, Bill. I looked in "Upgrading and Repairing PCs" also, and I think you're looking at the Phoenix Bios codes, rather than AMI. I did listen again, and the beep pattern I got was 2-8-2, which didn't match any of the listed AMI codes. I decided to try ignoring the initial 2 short beeps, and see what error was describe for 8 beeps in the AMI list. They indicated a problem in the video card. I checked, and sure enough, the video card wasn't properly seated. So, I still don't know the meaning of the initial and final 2 short beeps, but the problem is solved. Thanks again for the input.
