   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   |  JP1/2 through 9 are the BIOS address select. The factory  |
   | setting is C800 and is set with trace wires at JP1/jumpers |
   | 2, 3, 5, 6, and 9. BIOS address may be changed by cutting  |
   |  the traces and closing other pins, using the information  |
   |   in the table above. However, any modifications to the    |
   |             controller will void the warranty.             |
