  |               MISCELLANEOUS TECHNICAL NOTES                |
  |------------------------------------------------------------|
  |  JP1/jumpers 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. The 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!   |
