For assistance in locating the BIOS Part Number for your ATI graphics adapter, please refer to the following document:

Once you know your BIOS Part Number, you can determine which ATI CHIP is installed on the product using the following table.

Look up the BIOS Part number in the following table.  For example, if your BIOS part number is 113-38501-101, look for "113-38501" in the table.  Read the Chip Type from the middle column.

Note: If you're reading the BIOS Part Number right off the BIOS chip, you may find that the first three digits (112 or 113) are MISSING. See examples of BIOS chips here.
